Torque of a current carrying wire in magnetic field

In summary, the torque of a current carrying wire in a magnetic field is a measure of the rotational force exerted on the wire due to the interaction between the two. It can be calculated by multiplying the magnitude of the magnetic field, the length of the wire, the strength of the current, and the sine of the angle between them. The direction of the torque follows the right-hand rule and can change depending on the wire's orientation and the current's direction. Factors such as the strength of the magnetic field, current, wire length, and angle can all affect the torque. Understanding torque is crucial in explaining the behavior of current carrying wires in devices like electric motors and generators, and can aid in their design and optimization.

What is torque of a current carrying wire in magnetic field?

The torque of a current carrying wire in a magnetic field is the measure of the rotational force exerted on the wire due to the interaction between the magnetic field and the electric current flowing through the wire.

How is torque calculated for a current carrying wire in a magnetic field?

The torque can be calculated by multiplying the magnitude of the magnetic field, the length of the wire, the strength of the current, and the sine of the angle between the wire and the magnetic field.

What is the direction of the torque on a current carrying wire in a magnetic field?

The direction of the torque is perpendicular to both the magnetic field and the current, following the right-hand rule. This means that the direction of the torque can change depending on the orientation of the wire and the direction of the current.

What factors affect the torque on a current carrying wire in a magnetic field?

The strength of the magnetic field, the current flowing through the wire, the length of the wire, and the angle between the wire and the magnetic field are all factors that can affect the torque on a current carrying wire in a magnetic field.
