What is an advantage of using an electromagnet rather than a regular magnet?
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.
What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
Can you give me a sentence using electromagnet?
many people uses an electromagnet when working.
Can you give me an example of a simple sentence using the word electromagnet?
There is an electromagnet in that crane
An advantage to using an electromagnet is that they?
Can be turned off
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.
You can increase the strength of an electromagnet field by?
using a stronger ferromagnetic material for the core. :)
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.

How do you make a railway signal using electromagnet?
how to make road rail signal using electromagnet
How can you make an electromagent stronger?
there are two ways boy, first by increasing the number of colis 2. by using a stronger battery love, razor..

A coil of copper wire when connected to a flashlight cell becomes an electromagnet. What will make the magnet stronger?
Two things, either increase the voltage by adding another battery (to increase current in the coil), or increase the number of turns in the coil. We're assuming you wound your coil around some nice ferromagnetic material and are using that for a core.

What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
