Question

How can you determine the magnetic field around a current carrying conductor?
A. Left hand thumb rule
B. Right hand thumb rule
C. Sonometer
D. By rotating the conductor

Answer 1

Hint:The rate of charge flow is commonly referred to as current. We already know that stationary charges generate an electric field equal to the charge's magnitude. Moving charges emit magnetic fields that are equal to the current, so a current bearing conductor creates a magnetic effect around it. The subatomic particles in the conductor, such as passing electrons in atomic orbitals, are thought to be responsible for the magnetic field.

A magnetic field is generated around a current-carrying straight conductor. The magnetic field in the direction of the current is shown by the Maxwell right-hand thumb rule. If the right-hand thumb points in the direction of the current, the magnetic field direction due to the current is provided by the remaining curled fingers of the same hand. The curled fingers would be anti-clockwise while the thumb is up, and the magnetic field will be anti-clockwise as well, and vice versa.

The magnitude and position of a magnetic field are also important. As a result, it is a vector quantity denoted by B. (in the diagram given below). The magnetic field generated by a current-carrying conductor is proportional to the current and the distance between the point and the conductor. The magnetic field is perpendicular to the wire's path. If you coil the fingers of your right hand around the wire with your thumb pointed in the direction of the current, the direction in which the fingers curl would give you the magnetic field's direction.
