Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
Does the magnetic compass always point in a northern direction when placed on the earth?
No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!
Is Venus electromagnet?
No. Venus has no magnetic field.
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
How is an electromagnet different from a regular bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
Is an electromagnet what is changed by flipping the direction of the electrons which is controlled by the commutaor?
In an electromagnet, flipping the direction of electrons changes the magnetic field, which is controlled by the commutator.
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
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.
What happen to an electromagnet's field if the direction of the current ic reversed?
In that case, the magnetic field will also be reversed.
What happen when you change the direction of current in an electromagnet?
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
What are different words that involve magnets?
Electromagnet Superconducting magnet Ferromagnetic Magnetic needle Magnetic compass magnetic field. Hydro magnet Gyro magnet
What does a electromagnet create?
a magnetic field
Is an electromagnet always magnetic?
No. Only when an electric charge is put through the electromagnet.
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
