U-Shaped Electromagnet
Specifically designed to perform experiments of electromagnetism, the Altay’s U-Shaped Electromagnet encourages students to learn about the relationship between electricity and magnetism.
Resistance: approximately 30 Ω
Impedance at 50 Hz: approximately 50 Ω without keeper.
Equipment Needed:
Regulated DC Power Supply Unit – Code 2409.20
Iron fillings – Code 4612.12
Laws and principles investigated

experiment: visualize the magnetic lines of force
The electromagnet is used in many electric devices such as: electric bells, relays, circuit breakers, loudspeakers and microphones.
Strong magnetic fields can be achieved by coiling a wire around a piece of soft iron.
The soft iron becomes a magnet itself when the current begins to flow, and makes the magnetic field stronger.
