Question

Why does toroid have a higher magnetic field than a solenoid?

• A. It is magnetically efficient.
• B. It is a straight core.
• C. It has an open loop core.
• D. It has a closed loop core.

Answer 1

The correct option is D It has a closed loop core.

Due to the symmetry and being closed loop core.

Totoid has higher magnetic field and thus higher inductor and Q-facator
