Explanation:
Given that,
Voltage of household line, V = 110 V
Power of the hairdryer, P = 1650 W
During use, the current is about 1.95 cm from the user's hand.
(a) Power is given by :

(b) Again the power is given by :

R is resistance of the dryer

(c) The magnetic field produced by the dryer at the user's hand is given by :

Hence, this is the required solution.
Current will be

now just pluf in the values and Voila..
