Which magnet made by an electric current flowing through wires?
Electromagnet.
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
How can you strengthen an electromagnet?
make an electromagnet stronger by doing these things: * wrapping the coil around an iron core * adding more turns to the coil * increasing the current flowing through the coil.
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
True or False The strength of the magnetic poles in an electromagnet decreases with an increase in the number of turns of wire and the current flowing through them.?
F=N*I so directly proportional
Is an electromagnet a coil of wire with current flowing through?
Yes.
Which magnet made by an electric current flowing through wires?
Electromagnet.
Why magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
How can you make a electromagnet lose its magnetism?
by decreasing its current,by decreasing turns of coil
What makes a electromagnet stronger than a solenoid?
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
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.
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
What will only produce magnetism when current is flowing through it?
Any electrical conductor only will. Ah! You're fishing for "electromagnet".
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
Is an electromagnet created by electricity?
Yes. Electromagnets are named only because magnetism is caused because of electric current flowing through.
How can you strengthen an electromagnet?
make an electromagnet stronger by doing these things: * wrapping the coil around an iron core * adding more turns to the coil * increasing the current flowing through the coil.
