Question
What is Maxwell's corkscrew rule? For what purpose is if used?
Solution
If we imagine driving a corkscrew in the direction of a current, the direction in which we turn its handle is the direction of magnetic field.
This rule is used to find the direction of magnetic field if the direction of current is known.
When electric current flows vertically upwards, the direction of magnetic field produced is anticlockwise. Similarly, when electric current flows vertically downwards, the direction of magnetic field is clockwise.
Is there an error in this question or solution?
Solution What is Maxwell'S Corkscrew Rule? for What Purpose is If Used? Concept: Magnetic Effect of a Current.
