In a compass, a magnetized needle aligns itself with the Earth’s magnetic field, pointing toward the magnetic north. This allows users to determine direction relative to the Earth’s magnetic poles.
Magnets are used in various everyday applications, such as in fridge magnets, compasses, electric motors, speakers, and magnetic locks. They also play a critical role in industrial machinery and medical devices.
A permanent magnet has a constant magnetic field and does not require electricity. An electromagnet, however, needs an electric current to generate its magnetic field, and its strength can be controlled.
The strength of an electromagnet can be increased by increasing the electric current, adding more turns to the wire coil, or using a core with better magnetic properties, like soft iron.
