Simple magnetism and magnetic fields — practice question
A student studies the magnetic field in the space between two strong magnets. She arranges the magnets as shown in Fig. 4.1.
(a)[1]
She sets the magnets on a smooth surface with small pieces of adhesive putty (e.g. Blu Tack or Patafix), as shown in Fig. 4.1. Suggest why the pieces of adhesive putty are necessary.
(b(i))[3]
Describe how she uses a plotting compass to map the pattern of the magnetic field between the magnets.
(b(ii))[1]
On Fig. 4.1, draw the form of the magnetic field she sees inside the box outlined by the dashed lines.
