Have you ever looked at a stunning, light-shifting magnetic manicure on social media and wondered, "How do they get that perfect velvet glow?"
The secret isn’t just in the polish—it’s entirely in the tool and the technique.
If you’ve ever tried making a cat-eye look at home and ended up with a blurry, cloudy mess, the culprit is likely the way you're holding your magnet, or using the wrong shape for the design you want. Different magnets create entirely different magnetic fields, which move the iron particles inside your magnetic nail polish in unique ways.
In this comprehensive, salon-grade cat eye nail magnet tutorial, we will break down exactly how to use a nail magnet—including classic rectangles, cylinders, and advanced 5-in-1 tools—so you can achieve sharp, professional results every single time.
Key Pre-Application Steps: Essential Setup for Success
Before using a nail magnet, remember the golden rule of cat-eye gel polish:
Magnetic particles can only move while the gel is still uncured.
-
Apply a base coat and cure it under a UV/LED lamp.
-
Apply an even layer of cat-eye gel polish, but do not cure it.
It is important to note that the coating should not be too thin. It is recommended to apply a slightly thicker layer than regular color gel to ensure there are enough magnetic particles for proper movement, resulting in a fuller and more defined light effect.
(If you are using a nail tip stand, avoid magnetic or magnetized stands, as they may interfere with the magnetic field.)
1. How to Use the Classic Rectangular Magnet
The rectangular magnet is the most basic yet essential tool. Almost all nail designs begin by using it to create a wide effect, before building other effects on top.
Wide Effect Technique:
-
Place the narrow edge of the rectangular magnet parallel to one side of the nail surface, keeping a distance of about 3–5 mm. Hold it steady for 5–10 seconds.
You will see the magnetic particles quickly gather into a clean, sharp light band. -
Quickly move the magnet away.
-
Then place the rectangular magnet on the opposite side of the nail, again keeping the narrow edge parallel to the nail surface, and hold for 5–10 seconds.
You will see the light transition from a single line into a wider, fuller glow. -
Repeat this process on both sides 2–3 times. With each repetition, the light becomes brighter, more even, and more dimensional.
Alternatively:
-
Place the narrow side edge of the rectangular magnet parallel to one side of the nail surface, keeping a distance of about 3–5 mm. Hold it steady for 5–10 seconds. You will see the magnetic particles quickly gather into a clean, sharp light line.
-
Quickly remove the magnet.
-
Then use the smallest narrow edge of the rectangular magnet, and move it evenly and parallel along the opposite side of the nail. You will also see the light transform from a single line into a wider surface glow.
-
Repeat this process 2–3 times.
Pro Tip: Once the desired effect is achieved, immediately cure under a UV/LED lamp. Otherwise, the light pattern will gradually disperse over time.
Ombre Effect Technique:
Based on the wide light effect, place the narrow side of the magnet facing the fingertip, parallel to the nail surface at a distance of about 2–3 mm above the nail. Gently push the light from the cuticle toward the fingertip using the full narrow edge.
Stop at the desired position and hold for 2–3 seconds, then slowly lift the magnet away.
French Effect Technique:
Based on the wide effect, place the narrow side of the magnet vertically above the nail surface, keeping a distance of about 2–3 mm. Gently push the light from the cuticle toward the fingertip using the pointed corner.
Stop at the desired position and hold for 2–3 seconds, then slowly lift the magnet away.
Smile Line Technique:
Based on the French effect, place the broad face of the rectangular magnet at a 45° angle near the fingertip.
Straight Line Technique:
Based on the wide light effect, place the broad face of the rectangular magnet parallel above the nail surface at a distance of about 2–3 mm, hold for 3–5 seconds, then quickly lift it away.
Different angles create different light patterns:
-
Horizontal → horizontal light line
-
Vertical → vertical light line
-
Diagonal → diagonal light line
Zigzag Line Technique:
Based on the horizontal line effect, use the corner of the rectangular magnet, keeping it parallel above the nail surface, and gently push the light to the left or right to shift and reposition the highlight.

2. How to Use the Cylinder / Round Magnet (The Velvet Maker)
Circular or cylinder magnets emit a radial magnetic field. Instead of pulling particles into a line, they push the pigment away, making them the absolute secret weapon for soft, organic movement.
Wide Effect Technique:
-
Place the circular face of the cylinder magnet parallel to one side of the nail surface, keeping a distance of about 3–5 mm. Move it steadily and evenly from the fingertip toward the cuticle, parallel to the nail surface. You will see the magnetic particles quickly gather into a clean, sharp light band.
-
Quickly move the magnet away.
-
Then place the cylinder magnet on the opposite side of the nail and repeat the same motion, moving steadily from the fingertip toward the cuticle, parallel to the nail surface. At this point, the light will gradually expand from a single line into a wider, fuller glow.
-
Repeat this process on both sides 2–3 times. With each repetition, the effect becomes brighter, more even, and more dimensional.
Side Effect Technique:
On one side of the nail, use the circular face of the cylinder magnet and move it from the fingertip toward the cuticle, following a motion parallel to the C-curve of the nail.
Glass Bead Technique:
Based on the wide light effect, use the edge of the circular face of the cylinder magnet and move it in a circular motion above the nail surface, drawing circles over the nail.

3. Pattern-Forming Magnetic Tools
Whether you are assembling magnets yourself or using 4-in-1, 5-in-1, or even 8-in-1 magnet tools, the usage is very simple. After creating the wide effect and before curing, simply hover the magnet 2–3 mm above the nail surface for 3–5 seconds, and the pattern will instantly appear.
Key Curing Steps: Locking in the Design
Once the light effect reaches your desired result:
-
Quickly remove the magnet, making sure not to pass it over the design.
-
Immediately cure under a UV/LED lamp. Without curing, the magnetic pattern will gradually disperse over time.
