How to Make Magnets Stronger?


Magnets have been used for lots of applications from home to business. You can find magnetic devices in small headphones and large wind turbines. However, their magnetic forces decrease over time, and these magnets couldn’t function as expected. Therefore, several measures are taken to make them strong again. Let’s discuss how to make magnets stronger in detail.

How to Make Magnets Stronger? How to Make Magnets Stronger?

Check the Type of Your Magnets First

First of all, determine the type of your magnets.

  1. If the magnet turns out to be weak all the time, there is no way to strengthen it. Discard it and find a new one to complete the job. There are a variety of powerful magnets on our website. Visit our homepage and get a suitable magnet.
  2. If the magnet is a permanent magnet that has its magnetic field, you can recharge it using stronger magnets. Nd-Fe-B magnets, Sm-Co magnets, Al-Ni-Co magnets, and ferrite magnets are all permanent magnets. Stanford Magnets has been devoted to the manufacturing of quality permanent magnets for years.
  3. If your magnet belongs to electromagnets, you can adjust the electric current to get a stronger magnet because the magnetic forces of electromagnets come from the current. Their magnetism disappears when the current stops.

Here is a list of the difference between permanent magnets and electromagnets. You can check the table below to figure out where your magnets belong. Table 1 Difference between Permanent Magnets and Electromagnets

  Permanent Magnets Electromagnets
Magnetism The strength relies upon the nature of the material used. The strength depends on the amount of flow of current.
Poles The poles of permanent magnets are fixed. Its poles can be changed with the flow of current.
Sizes The size is relatively small since they usually have stronger magnetism. The size and shape can be customized according to the specific situation.

Methods to Make Weak Ferromagnets Strong Again

You can make your weak ferromagnets strong again by the following methods.

  1. Relocate your magnets to avoid being affected by certain environmental factors.

Magnet power can be affected by temperature, radiation, corrosion, and external magnetic fields in the surroundings. So, we are supposed to put magnets away from microwave ovens, stoves, and other electric devices to avoid heat and radiation. Putting them in a freezing temperature is also of great help.

  1. Recharge these weak magnets with more powerful magnets.

Relocating is just a quick fix. In order to get a strong permanent magnet again, put your weak magnet next to a powerful magnet. The stronger magnetic field will pull the electrons of the weak magnet back into alignment. Then, your magnet could regain its strength.

  1. There are many more useful ways to recover the magnetic forces again.
  2. Striking works for iron bar magnets. Hammer one end of the magnet hard repeatedly to regain its strength. Stack magnets together might work temporarily.

Ways to Make Electromagnets Stronger

It is much easier to make electromagnets stronger. You just need to adjust the current or the number of currents circulated to enhance your magnet’s strength.

  1. Increase the winding circle to get more current circulation.
  2. Reduce resistance by using more conductive wires.
  3. You can employ higher voltage to increase the electric current. The relevant formula is V=IR. V refers to voltage, and R means resistance. The current (I) can be increased if the applied voltage increases.
  4. Switching the alternating current to the direct current works as well. We choose the direct current because the magnetic polarity changes under altering current and has negative impacts on the establishment of magnetic strength.


Learn about different kinds of magnets, and choose the right method to make your weak magnets strong again. Permanent magnets need the help of large and powerful magnets, while electromagnets require rising currents. Hope that you can get a stronger magnet again.
