Why do the magnetic forces acting on the coil change as the current running through the coil changes?
The magnetic forces acting on the coil change with the current because the strength of the magnetic field produced by the current in the coil is directly proportional to the current flowing through it. As the current changes, the magnetic field strength changes, leading to a change in the magnetic forces acting on the coil.
Which type of current is produced by a wire breaking magnetic field lines and changing the polarity?
An alternating current (AC) is produced when a wire cuts through magnetic field lines and experiences a change in polarity. This phenomenon is known as electromagnetic induction, where the changing magnetic field induces a current in the wire.
How do you reverse the magnetic field of an electromagnet?
To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
Why does a compass change direction when it is near a current-carrying wire?
A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.
What is produced around a wire that has a current?
Magnetic field.

What is lenz law of electromagnetic induction?
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
How do you reverse the magnetic field of an electromagnet?
To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.
What are the three characteristics of magnetic field produced by a current?
.
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
Why does a compass change direction when it is near a current-carrying wire?
A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
What is electricomagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
