What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What does an electromagnet operator do to release metal attached to the electromagnet?
burat
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
What happens when a compass is placed next to a electromagnet?
the arrow goes to the magnet
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
What happens when you remove the power source from an electromagnet?
It loses it's magnetism, or most of it.
What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What happens to the strength of electromagnet when more turns of wire were used?
it will caught just a little paper clip
What happens to the strength of magnetic force in an electromagnet when increasing the current through the coil?
The strength is increased, this is how Roller Coasters operate.
Which is better a permanent magnet or an electromagnet?
electromagnet
