Why are electromagnets more useful than real magnets??​

Answer 1

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

• Control of Magnet Strength One of the most important features of an electromagnet is the ability to change its magnetic force.

• When no electric current flows through the magnet's wires, it has no magnetic force.

• A large current gives the magnet a bigger force, able to lift or pull heavier objects

• However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

• Strengths of permanent and electromagnets

As number of turns of coil are more in magnet .

Then strength in magnet will be more. As electromagnet have more turns in coil. They are strong than normal magnet.

Hope it will help you
