How is electricity transformed into motion?
A motor transforms electricity. Inside the motor, there is a permanent magnet and an electromagnet, which can rotate. When the circuit is closed, the electromagnet is constantly repelled and attracted to the permanent magnet. This will cause the electromagnet to turn. It also causes anything that is attached to the electromagnet to turn, causing motion.
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
What kind of energy does an electromagnet make?
Electrical to Mechanical

Which is not a way to make an electromagnet stronger?
To chew on it.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
How does an electromagnet make the sounds you hear in headphones?
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.

Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
Would spinning the loops on an electromagnet make it stronger?
Yes, if you increase the number of coils or loops in an electromagnet, it's power increases.
How do you make an electromagnet weak?
reducing the number of coils around the core or by reducing the current in an electromagnet, will cause the magnetic power to weaken.
