To find the percent increase in the magnetic field \( B \) when the space within a current-carrying toroid is filled with aluminum, we can follow these steps: ### Step 1: Understand the Magnetic Field in a Toroid When there is no aluminum present, the magnetic field \( B_0 \) in a toroid can be expressed as: \[ B_0 = \mu_0 H \] where \( \mu_0 \) is the permeability of free space and \( H \) is the magnetic field intensity. ...
