What are things that all electrical motors use to make motion?
Rotating magnetic fields.
Do bats use the earths magnetic fields?
no
The procedure to make a magnetic bell?
You need wire, a nail, and some steel sheet cut from a can. Then you need a bell. Wind the wire round the nail to make an electromagnet. Nail the strip of steel to a wooden block. Fix the electromagnet so that it pulls the steel when switched on. Then you need to make a switch which will be another arrangement of thumbtacks. So when the magnet switches on the steel pulls away from the tack and breaks the circuit. The steel hits the bell but it returns dues tothe magnet being switched off.
What technique involves the use of magnetic fields and radio waves to produce images of the brains soft tissue?
MRI - Magnetic Resonance Imaging

What would happen if a pigeon detected a magnetic field?
There are theories around that some birds can actually detect magnetic fields, which they use to navigate on long migrations.
