Why magnetic field inside the current carrying conductor is zero?

Answer: Electric field inside a current carrying conductor is zero as the charges inside it distributes themselves on the surface of the conductor. The net charge in the current carrying wire is zero.

Does a magnetic field exert a force on a still charge?

It is important to note that magnetic field will not exert a force on a static electric charge.

Why is the net charge on a current carrying wire zero?

The net charge in a current- carrying wire is zero. As they are not moving so there is no force on them, so the force is only due to the moving electrons in the wire.

Why is a force exerted on a current carrying wire in a magnetic field?

Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges).

What is the net magnetic field inside a conductor?

The magnetic field inside a conductor with uniform current density J = I/πR2 can be found with Ampere’s Law. Inside the conductor the magnetic field B increases linearly with r. Outside the conductor the magnetic field becomes that of a straight conductor and decreases with radius.

What causes magnetic force?

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Their movement generates an electric current and causes each electron to act like a microscopic magnet.

What is the net charge on a current carrying conductor?

zero
The net charge on a current carrying conductor is zero.

What is the charge on a current carrying wire?

The current in a wire is due to flow of free electrons in a definite direction. But the number of protons in the wire at any instant is equal to number of electrons and charge on electron is equal and opposite to that of proton. Hence net charge on the wire is zero.

On which the force exerted on the current carrying rod when it is placed in a magnetic field depends?

The direction of force on the conductor depends upon the direction of current and the direction of magnetic field. The displacement of the rod is maximum when the direction of current is at right angles to the direction of the magnetic field.

What is the condition when magnetic field intensity is zero?

Explanation: Electric field will be zero inside a conductor and magnetic field will be zero outside the conductor. In other words, the conductor boundary, E will be maximum and H will be minimum.
