Q: In a toroidal solenoid, the magnetic field inside the toroid is:
Solution: The magnetic field inside a toroidal solenoid is uniform and non-zero, depending on the current and the number of turns.
Steps: 5
Step 1: Understand what a toroidal solenoid is. It is a coil of wire shaped like a donut (torus).
Step 2: Know that when electric current flows through the wire, it creates a magnetic field.
Step 3: Recognize that the magnetic field inside the toroid is different from outside. Inside, it is strong and uniform.
Step 4: The strength of the magnetic field depends on two things: the amount of current flowing through the wire and the number of loops (turns) of the wire.
Step 5: Remember that outside the toroid, the magnetic field is very weak or nearly zero.
