Frequently asked questions
What is Topic 12: Magnetism and the motor effect?
Magnetism, magnetic fields and the motor effect. 9 lessons in 2 subtopics.
What is the left-hand rule?
The left-hand rule, Fleming's left-hand rule, shows the direction of the force on a current-carrying conductor in a magnetic field. The The Motor Effect and Fleming's Left Hand Rule notes cover this in full.
Is aluminium magnetic?
Aluminium is not magnetic, and neither is copper, even though they are metals. The Introduction to Magnetic Fields notes cover this in full.
Is copper magnetic?
Copper is not magnetic, even though it is a metal; only iron, steel, cobalt and nickel are magnetic materials. The Introduction to Magnetic Fields notes cover this in full.
What is a solenoid?
A solenoid is a coil of wire that produces a magnetic field when current flows through it. The Solenoids and Electromagnets notes cover this in full.
How does a compass work?
A compass contains a magnetised steel needle, a small bar magnet, that can rotate freely on a pivot. The Earth's Magnetic Field and Compasses notes cover this in full.
What is an electromagnet?
An electromagnet is a solenoid with an iron core that can be switched on and off by controlling the electric current. The Solenoids and Electromagnets notes cover this in full.
How do you use Fleming's left-hand rule?
Fleming's left-hand rule uses the thumb, first finger and second finger held at right angles. The The Motor Effect and Fleming's Left Hand Rule notes cover this in full.
What is a magnetic field?
A magnetic field is the region around a magnet where a force acts on another magnet or on a magnetic material: iron, steel, cobalt and nickel. The Introduction to Magnetic Fields notes cover this in full.
