Question

Which rule is used to find a direction of current in solenoid

Answer 1

Answer:

Explanation:

To find the polarity of a solenoid, you can use the right-hand rule for current (or left-hand rule for electrons since they go in the opposite direction to the current). To do this, point your right thumb in the direction that the current travels in the coiled wire in the solenoid and curl your fingers.* The direction your fingers point will determine the direction of the magnetic field created by the current.
