Check the Magnetic Power
After arranging the magnets, it is time to check their magnetic energy. This step is essential to make sure that the magnets have ample holding energy to your meant software.
Everlasting Magnet Pull Power Tester
Utilizing a everlasting magnet pull energy tester is probably the most correct technique to measure magnetic energy. This system measures the drive required to tug a magnet away from a flat floor or one other magnet. The unit of measurement is usually in kilos (lbs) or newtons (N).
Steps to Check Magnetic Power:
1. Place the magnet on a flat, non-magnetic floor.
2. Zero the pull energy tester.
3. Place the pull hook or probe immediately above the middle of the magnet.
4. Slowly apply an upward drive till the magnet separates from the floor or different magnet.
5. Document the studying on the pull energy tester.
Components Affecting Magnetic Power:
| Issue | Impact |
|---|---|
| Magnet measurement and geometry | Bigger magnets typically have larger pull energy. |
| Magnet grade | Larger grade magnets have larger magnetic vitality and pull energy. |
| Temperature | Excessive temperatures can weaken magnets. |
| Distance from magnetic materials | Magnetic energy decreases with distance from the magnetic materials. |
| Orientation | Magnets oriented perpendicularly to the floor have larger holding energy. |
