How To Make Stainless Steel Magnetic

Only some stainless steel is magnetic and can be magnetized. The composition of stainless steel varies, and any stainless steel with nickel in it is difficult to magnetize, although cold-rolling it, stretching it or stressing it in other ways does increase its magnetic potential. Series 200 and 400 stainless steel do not have nickel, are naturally magnetic and can be magnetized. Using simple methods of magnetizing metal produces only a temporary magnet. To permanently magnetize something, you need a large alternating-current magnetic coil, which is not generally available in most homes.

Step 1

Strip 1 inch from both ends of your insulated wire, using the wire stripper.

Step 2

Wrap the insulated wire around the stainless-steel object multiple times without overlapping the wires; form a coil around it. Leave enough wire to easily reach your battery.

Step 3

Place the object to be magnetized on an insulated surface, such as wood, rubber or cement. Don't hold the object while magnetizing it.

Step 4

Connect one end of the wire to the positive terminal of your battery. Depending on the battery type, you will wrap the bare wire around the terminal and screw down the connecting cap.

Step 5

Put on your safety glasses. Hold the other end of the wire with the insulated needle-nose pliers. Brush the bare end of the wire against the negative terminal of the battery. The battery will spark when you do this. Repeat this action three to six times.

Step 6

Disconnect the wiring from the positive terminal of the battery. Unwrap the wire from around your stainless-steel object. It is now temporarily magnetized.

Things Needed

  • Insulated wire
  • Wire stripper
  • Insulated needle-nose pliers
  • 400 series stainless-steel item
  • 12-volt dry-cell battery
  • Safety glasses

TL;DR (Too Long; Didn't Read)

To magnetize larger pieces of stainless steel, touch the negative terminal of the battery with a bare wire more times.
