Question

. How will you determine the polarity when current is passed
through a solenoid? Suggest methods for increasing the strength
of the magnetic field around a current carrying solenoid.​

Answer 1

Answer:

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.
