उत्तर
Magnetic field (B) produced by current-carrying wire is directly proportional to the current (I) flowing through the wire.
If the current is increased then the magnetic field produced is stronger and vice-versa. So, deflection in the compass will be more when the current flowing through the wire will be increased.
