Worksheet: Magnetic Fields

In this worksheet, we will practice correctly drawing the field lines of the magnetic field created by a magnet and relating field lines to the force experienced by two magnets.

Q1:

  • A
  • B
  • C
  • D

Q2:

Which of the four diagrams correctly shows the direction that a plotting compass will point when it is placed near to a bar magnet?

  • A
  • B
  • C
  • D

Q3:

The image shows two diagrams for the magnetic field lines between two very wide flat permanent magnets. Which diagram shows magnetic attraction?

  • A
  • B

Q4:

Which of the four diagrams correctly shows the field lines for the magnetic field between two very wide flat magnets that are placed near to each other? Red represents the north pole of the magnets and blue the south pole.

  • A(b)
  • B(a)
  • C(c)
  • D(d)

Q5:

Which of the two diagrams correctly shows the magnetic field lines between two flat very wide magnets that are placed near to each other? Red represents the north pole of the magnets and blue the south pole.

  • A
