Question

Write 2 advantages of electromagnets over permanent magnets

Answer 1

Answer:

the Electromagnet are

Explanation:

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Answer 2

Answer:

Advantages of electromagnets

• Strength of magnet can be increased by increasing the current flowing through electromagnet while in permanent magnet strength remain sames.
• Magnetic field lines can be quickly change but in permanent magnet it remain sames.
