Question
Describe how to use the right-hand rule to find the magnetic field of a current-carrying wire.
Solution
Sure, here are the steps to use the right-hand rule to find the magnetic field of a current-carrying wire:
-
First, extend your right hand flat, with your thumb pointing straight up.
-
Imagine the wire is running in the direction of your thumb. This represents the direction of the current.
-
Now, curl your fingers. The direction in which your fingers are curling represents the direction of the magnetic field.
-
The magnetic field circles around the wire in the direction that your fingers are curling.
-
If the current direction changes, you would change the direction of your thumb, and the curl of your fingers (magnetic field) would also change accordingly.
Remember, this rule is based on the conventional current direction (from positive to negative). If you're dealing with electron flow, the direction would be opposite.
