How to Make an Electromagnet

Studying Oersted's Experiment and electromagnetism led to new ways of harnessing electric power. One way is the electromagnet, which has many practical applications. This experiment shows you how to make an electromagnet.

Materials You Will Need:

  • Energizer® Power Pack
  • Small, non-metallic bowl
  • Number 20 nail
  • Thumbtacks
  • (1) 6" piece and (1) 2-yard piece of number 22 insulated copper bell wire with approximately 1" of insulation stripped off all ends
  • Switch or alternate commercial knife blade switch
  • Paper clips

Please Read Carefully!

All experiments use safe, low-voltage battery power. Household electrical current contains high voltage that could cause serious injury. DO NOT use household electrical current for any of these experiments. ALL experiments should be conducted under adult supervision.

  • Carefully follow wiring instructions for each experiment. Improper wiring can result in battery leakage and/or rupture.
  • DO NOT take a battery apart. Contact with internal battery material can cause injury.
  • DO NOT dispose in fire, recharge, put in backwards, or mix with used or other battery types. This may cause batteries to explode, leak and cause personal injury.
