What is the magnetic field inside a toroidal solenoid? (2023)
Step 1: Understand what a toroidal solenoid is. It is a coil of wire shaped like a donut.
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 toroidal solenoid is uniform, meaning it is the same at every point inside.
Step 4: Learn the formula for the magnetic field inside the toroidal solenoid: B = (μ₀NI)/(2πr).
Step 5: Identify the variables in the formula: μ₀ is the permeability of free space, N is the number of turns of the wire, I is the current flowing through the wire, and r is the distance from the center of the toroid.
Step 6: Use the formula to calculate the magnetic field by plugging in the values for N, I, and r.
