Lesson details
Key learning points
- When there is an electric current in a wire, there is a magnetic field around the wire.
- When there is an electric current in a coil of wire, the magnetic field around each loop adds to make a stronger field.
- An electromagnet is made by wrapping a coil of wire around a core.
- An electromagnet is a magnet that can be turned on with an electric current, and turned off.
Keywords
Magnetic field - this exerts a force on magnets and magnetic materials
Coil - a wire wound round in loops and looks like a spring
Core - the centre of an electromagnet around which a wire is wound to make a coil
Turn - a single loop of wire in a coil
Electromagnet - a magnet made using a coil, a core and a power supply
Common misconception
A magnetic field is the same as the electric field around a charged object.
Demonstrate that a balloon with a static electric charge does not affect the magnet in a plotting compass.
