Which part of the electromagnets turned into a magnet when electricity flows through a coiled wire?
Battery
Copper wire
Iron Nail
Bulb
Electric currents produce _____________
electron clouds
magnetic fields
sound waves
How can the strength of an electromagnet be increased? (mark all that apply)
increase the current flowing through the coil
increase the number of coils
add an amplifier to it
put iron core inside the coil
An electromagnet is temporary magnet made by placing a piece of iron inside a current carrying coil of wire. The more loops of wire, the stronger the magnetic field. The stronger the current, the stronger the magnetic field.
