What can affect the strength of an electromagnet?
The power of the battery controlling it.
What is the difference from a normal magnet to an electromagnet?
An Electromagnet is magnetic..... It can also be switched between positive and negative by the power source being turned around(battery)
What device use magnet and electricity?
Electromagnet
How does a doorbell use an electromagnet?
The electromagnet is only part of the mechinism the whole item is called a solenoid which has a magnetized rod inside the electromagnet when 24 volts is applied the solenoid springs out of the coils of the electromagnet striking the bell. When released the rod returns by use of a spring and strikes another bell. Ding, Dong.
When would you want to use an electromagnet rather than a permanent magnet?
When you need a magnet you can turn on and off an electromagnet is used.
How does an electromagnet turn on and off?
They turn on and off by taking the battery out and putting it back in or if it has a switch then you could use that.
What does a battery contribute to an electromagnet to help it work?
A core
What can affect the strength of an electromagnet?
The power of the battery controlling it.
What is used to produce an electromagnet?
A Battery, wire, nail/metal cylinder.
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
What object is not needed for making a electromagnet?
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
What is the difference from a normal magnet to an electromagnet?
An Electromagnet is magnetic..... It can also be switched between positive and negative by the power source being turned around(battery)
What is a nail wrapped around a wire and connected to a battery called?
it is called an electromagnet
Is a electromagnet with a six volt lantern battery really powerful or not?
Is a eletromagnet with a six volt lantern battery really powerful or not?
How do you use a electromagnet?
electromagnetically
What is an electricity magnet?
An electromagnet is a device that produces a magnetic field with the use of DC electricity. A simple electromagnet has a coil of wire wrapped around an iron core. A simple experiment would be to wrap a copper wire around an iron nail then connect both ends of the wire to a small battery. You will notice the nail is magnetized as long as the battery is connected.
