An electromagnet works on the principle of the magnetic effect of electric current. It is formed when a strong magnetic field is produced inside a solenoid to magnetise a piece of a magnetic material like soft iron. Electromagnets are made out of a coil of wire (wire curled in series). This is more effective in producing a magnetic field than just a wire running straight.
- The magnetic effect is directly proportional to the number of wire turns on the electromagnet.
- As a result of the greater number of turns of wire on the pahelis electromagnet, it will attract more pins. As a result, the pahelis electromagnet is the most strong electromagnet.
