What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
Name two deviceswhich use currentcarrying conductor and magnetic field?
Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.
When a charge moves in the same direction as the magnetic field lines the magnetic force is?
Perpendicular to both the current and the magnetic field.
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.

Does current affect electromagnetism?
Does current affect electromagnetism? No. Does current affect magnetic fields? Yes. The laws (Maxwell's Equations) pertaining to electromagnetism is constant and will not change regardless of current applied. However, Maxwell's equations does dictate that a change in current will essentially result in a change in magnetic fields. Current flow will produce a magnetic field perpendicular to the current direction.
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.
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".

How do you know that a force is negative or positive in relation to magnetic field?
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.

Flow of the current.
