An electromagnet is a device that creates a magnetic field by passing a current through the electrical conductor. It typically consists of an insulated copper wire wound into a coil (often called a solenoid) which may of may not have a ferromagnetic material within the centre of the coil to boost the performance of the electromagnet. Electromagnets have many uses, the main uses based on the electromagnet’s ability to attract ferromagnetic materials towards it (e.g. lifting applications).
The Simply Science Electromagnet kit (bottom left of picture) has is everything a child needs to build a simple electromagnet and learn how it works. It includes Alnico North/South bar magnet, wooden block, nail, screws, metal plates (key switch), 5 feet of insulated wire and instruction booklet. (6-volt battery required but not included). It is aimed for children aged 3 and upwards – adult supervision is recommended.
The Science Discovery Electromagnet kit (right side of picture) allows you to build a doorbell, telegraph system and even a catapult all using a true electromagnet. The professionally boxed Science Discovery Electromagnet kit includes: disc, latch and neodymium magnets, compass, straws, wires, sand paper, switch plates, wood screws, nails, light bulbs, battery holders, iron filings, pre-drilled wood blocks and light emitting diode (LED). It comes with a comprehensive activity book that includes 6 experiments and 6 projects. It is aimed for people aged 10 and upwards – adult supervision is recommended.
