How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?

A magnet cannot use words to create an electric current.
A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.

Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.
What is magnetic in electromagneticism?
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
How do the electric and magnetic field of an electromagnetic wave regenerate each other?
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
A device that produces a magnetic field by an electric current?
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
When there is a sudden collapse of a magnetic field in or around a solenoid. what happens?
Electric current will be induced in such a way that the flux of the magnetic field will be constant and thereby the induced current will create magnetic field in the same direction. This is what we call Lenz's law(law of conservation of energy).
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
When an electric current is passed through a coil what does this create?
A magnetic field.
How can produce an electric current by means of electric magnetic induction?
Create relative motion between a magnetic field and a loop of wire.
Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.

When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
What happen to magnetic compass if the current is changed?
If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.
How do the electric and magnetic field of an electromagnetic wave regenerate each other?
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
Can we create magnetic field to electric field?
we can create electromotive force (and electric current) by changing magnetic field linked with a conductor by the principle of electromagnetic induction which is governed by the Faraday's and Lenz's law. But electric field is created by statical electricity.
Why electric not attract iron objects when current is passed through it?
Any electric current does generate a magnetic field, but it might be a very weak magnetic field that you would not notice. In order to create a powerful electromagnet, wire is wrapped around a ferromagnetic core, typically hundreds or thousands of times. Each coil of the wire adds to the magnetic field. But unless the current is extremely strong, a single straight wire produces a magnetic field that's quite weak, but it IS strong enough to deflect a nearby magnetic compass.
What do moving electrical charges create?
-- Electric charge that's moving is the definition of electric current.-- It creates a magnetic field in its neighborhood.
Who discovered that electric current going through a wire can create a magnetic field?
Hans Christian Ørsted
