Aluminium is not magnetic, and neither is copper, even though they are metals. The Introduction to Magnetic Fields notes cover this in full.
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.
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.
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.
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.
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.
The right-hand rule finds the direction of the magnetic field around a current-carrying conductor: the right thumb points in the direction of conventional current, and the fingers curl in the direction of the magnetic field lines. The Currents and Magnetic Fields notes cover this in full.
Outside a solenoid, the field lines curve from one end to the other like those of a bar magnet, so one end is a north pole and the other a south pole. The Solenoids and Electromagnets notes cover this in full.
