Question

Will increasing the temperature of the solenoid decreases the magnetic force of the solenoid

Answer 1

The resistance of the wire willincreases with heating it. When we aredecreasing the temperature thestrength of electric field also decreased, decreasing the temperature just increase its drift velocity. Because of atomic vibration isdecreased. And the resistance of the wire decreased.

Answer 2

Answer:

$\mathtt \pink{ \xcancel{d B = \frac { M _ { 0 } n d x I a ^ { 2 } } { 2 [ ( r - x ) ^ { 2 } + a ^ { 2 } ] ^ { 3 / 2 } }}}$
