A long solenoid has a diameter of 15.3 cm. When a current i exists in its windings, a uniform magnetic field of magnitude B = 32.8 mT is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 5.15 mT/s. Calculate the magnitude of the induced electric field (a) 2.99 cm and (b) 11.7 cm from the axis of the solenoid.
Here we apply Faraday's law of electromagnetic induction and concept of induced electric field.
Magnetic field inside solenoid (Long Solenoid) will always be along the axis of - Solenoidi. Also magnetic field inside Long Solenoid ub. constant • throughout space inside. (a) Magnetic flux through circular loop of radius & to d = B. Ã =
