Question
Magnetic field outside a solenoid is:
Open in App
Solution
The correct option is C Negligible
A long straight coil of wire can be used to generate a nearly uniform magnetic field similar to that of a bar magnet. Such coils, called solenoids, have an enormous number of practical applications. The field can be greatly strengthened by the addition of an iron core. Such cores are typical in electromagnets.Magnetic field outside a solenoid is negligible.
