Answer:
a) : solenoid
b) : strength of solenoid depends upon
(i) no. of turns
(ii) electric current, distance of turn
Explanation:
a) solenoid is made up by many circular turns which is wound on soft iron of cylindrical shape by insulated copper wire
b) if no.of turns increased then the magnetic effect will also increase and if electric current is increased the magnetic field will increase and if distance of loop increase the magnetic field will decrease
