Devices that make use of electromagnets include electric motors, doorbells, MRI machines, loudspeakers, and generators. Electromagnets are also used in car starters, relays, and magnetic levitation trains.
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
By connecting the coil of wire to a battery, you create an electromagnet. When you place the iron bar inside the coil, the electromagnet magnetizes the bar. This setup is commonly used in electromagnets and devices like electric motors.
You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
No, a flashlight does not contain an electromagnet. Flashlights typically use batteries to power a light bulb or LED for illumination.
Solenoid valves, magnetic contactors, motors.
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.

No.
yes it does
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
