Electromagnets may be used for a wide veriety of things, from scrap cranes, electrical componants such as solenoids and relays, or in science for partacle acceleration and mass spectroscopy.
they are good for when you want a magnet that can be turned off to release whatever is magnetized to it i made one for fun to pick up steel shavings off the shop floor it is hard to clean off a conventional magnet that you cannot turn off
electromagnetically
power drills are one of the many things that have electromagnets.
yes it does
No.
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.
An electromagnet drives the stereo speaker to provide the sound.
An electric motor typically uses one electromagnet and one permanent magnet to create a magnetic field that interacts to produce motion. The electromagnet's field can be easily controlled by varying the electric current, allowing the motor's speed and direction to be changed. The permanent magnet provides a fixed magnetic field that interacts with the variable field of the electromagnet to generate the rotational force needed for the motor to work.
Use an electromagnet.
electromagnetism
To have a magnet that can be turned on and off.
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.
Yes, you would be able to use electromagnets in space.
