Can be turned off
A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.
An advantage of using an electromagnet in an electric motor is that its magnetic field can be easily controlled by adjusting the current flowing through the coil, allowing for variable speed and torque control. This makes electromagnets more versatile compared to fixed-strength permanent magnets in electric motors.
The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
Using a stronger battery can increase the current flowing through the electromagnet, which in turn can increase the strength of the magnetic field produced by the electromagnet. So, a stronger battery can result in a stronger electromagnet.
Increasing the resistance in the wire, reducing the number of coils in the electromagnet, and using a weaker power source will all result in a weaker electromagnet.

The electromagnet can be turned on and off depending on whether it's needed or not.

Electromagnets are widely used now. Instead of traditional magnets.

Sure! An electromagnet is a type of magnet that attracts objects when an electric current flows through it.
That is an electromagnet.
An electromagnet can be turned on and off by controlling the electric current, giving it more versatility in applications. Additionally, the magnetic strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it.
