Electro Magnets can work without battery power, hook up a really powerful solar panel and a resister to circulate an even current, add strands of copper wire and coil them around a tube to make them circular. hook them up to the solar panels to make the electro magnet's power circulate through the wire!! I tried it and its fun!

Everytime i turn on myr accessories like my radio why does it it drain your battery?
If you use the radio without the engine running you will eventually discharge the power from the battery. It should be fine for a couple of hours, If not, your battery may need replacing.
How do you listen to radio without running battery down?
Turn the ignition key to the accessory position which is normally counterclockwise. Only the radio will be drawing power. If you have a good battery you could listen for a couple of hours without running the battery down. Any longer and the battery may go dead. Make sure that the headlights are off; these may still remain on when the key is in the accessory position. Headlights will drain the battery very quickly. It may also be advisable to run the engine for a few minutes every half-hour or so, to recharge the battery.
Why is my phone is battery is dying while it is on the charger?
It may be that your battery is old. Rechargeable batteries work best when they're allowed to completely 'die' before recharging. Most people don't allow that to happen (me included !) - and thus the battery's life is shortened.
What does a battery contribute to an electromagnet to help it work?
A core
How does a scrap heap crane work?

What can affect the strength of an electromagnet?
The power of the battery controlling it.
How do you get your cellphone to work without a battery?

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
Does computer work without electricity?
