Right Hand Thumb Rule to Find the Direction of Magnetic Field
Right Hand Thumb Rule to Find the Direction of Magnetic Field: Overview
In this topic, we will discuss the right-hand thumb rule that explains the directions of the magnetic field and electric current. For easy understanding, the concept is well explained through examples and illustrations.
Important Questions on Right Hand Thumb Rule to Find the Direction of Magnetic Field
State right hand thumb rule to find the direction of the magnetic field around a current carrying conductor. How will this field be affected on:
Changing the direction of flow of current?
State right hand thumb rule to find the direction of the magnetic field around a current carrying conductor. How will this field be affected on:
(i) Increasing the current through the conductor
(ii) Changing the direction of flow of current?
The direction of magnetic field produced by a current-carrying straight conductor can be found using:
When a straight conductor is carrying an electric current
A constant current flows in a horizontal wire in the plane of the paper from east to west as shown in figure. The direction of magnetic field at a point will be North to South:
A circular loop placed in a plane perpendicular to the plane of paper carries a current when the key is ON. The current as seen from points A and B (in the plane of paper and on the axis of the coil) is anticlockwise and clockwise respectively. The magnetic field lines point from B to A. The N-pole of the resultant magnet is on the face close to:
