Why magnetic field is created around a current carrying conductor?

Why magnetic field is created around a current carrying conductor?

Current is generally defined as the rate of flow of charge. The same principle can be applied here, moving charges produce magnetic fields which are proportional to the current and hence a current carrying conductor produces magnetic effect around it. …

Does a current carrying conductor produce magnetic field?

A wire carrying electric current will produce a magnetic field with closed field lines surrounding the wire. The Biot-Savart Law can be used to determine the magnetic field strength from a current segment.

How does the strength of the magnetic field due to a current carrying coil change as its radius is decreased justify your response?

Answer. Biot Savrat Law affects the strength of magnetic field induced due to current flowing through the loop. Explanation: (1)When the loop’s radius is decreased as magnetic field strength formula is inversely proportional to radius of the loop, becomes double of the magnetic field strength.

What type of magnetic field pattern do we get around a straight conductor carrying current?

The Magnetic field lines around a straight conductor carrying current are concentric circles whose centres lie on the wire. The direction of magnetic field lines can be determined using Right-Hand Thumb Rule.

What are the factors that affect the strength of magnetic field of a straight current carrying conductor?

Answer. It is directly proportional to the current passing in the wire and inversely proportional to the distance of that point from the wire. so, greater the current in a wire, stronger will be the magnetic field produced.

How can we increase the strength of magnetic field for a straight current carrying conductor?

The force on a current carrying conductor in a magnetic field is increased by:

1. By increasing the current flowing in the conductor.
2. by increasing the strength of magnetic field.
