How To Recharge A Horseshoe Magnet

A horseshoe magnet attracts iron and metal objects. Magnets produce a magnetic field and, over time, may start to lose their strength. There are a few ways you can charge a horseshoe magnet to restore its strength.

Step 1

Get an electromagnetic charger. This type of charger is made of metal coils and an iron base. The metal coils produce a magnetic field that is able to transfer magnetic energy to the weak magnet. You can either purchase an electromagnetic charger or a kit from which you can assemble your own magnet charger. These are mostly available at craft supply stores.

Step 2

Wrap a few strips of paper around the charger's coils. To induce the magnetic field, connect the wire that is between the coils.

Step 3

Place the horseshoe magnet on top of the charger's coils. Make sure the magnet's poles are leaning in opposite directions from the charger's poles; the magnet's north pole should be over the charger's south pole and vice versa.

Step 4

Charge the magnet for 1 minute. While it charges, open and close the switch that is between the coils of the charger. Do this three to four times for 4 seconds each.

Step 5

Remove the magnet from the charger immediately.

Step 6

Disconnect the switch that is between the charger's coils.

Step 7

Recharge whenever you find the magnet's strength fading.
