Questions & Step-by-Step Solutions

In a toroidal solenoid, how does the magnetic field strength depend on the number of turns per unit length?
  • Step 1: Understand what a toroidal solenoid is. It is a coil of wire shaped like a donut.
  • Step 2: Know that the magnetic field is created when electric current flows through the wire.
  • Step 3: Learn that the number of turns per unit length refers to how many loops of wire are in a certain length of the solenoid.
  • Step 4: Realize that more turns per unit length means more loops of wire in the same space.
  • Step 5: Understand that more loops create a stronger magnetic field because the magnetic effects add up.
  • Step 6: Conclude that the magnetic field strength increases directly with the number of turns per unit length.
