At the poles 3 of 18 How is direction of magnetic field found? Using a compass 4 of 18 What does the compass contain? A bar magnet 5 of 18 Closer field lines mean? stronger magnetic field 6 of 18 Earth has its own ..... ...... due to.... ..... magnetic field, earth's core 7 of 18 Where does the needle in compass point? North to South 8 of 18 How to plot magnetic field around a magnet? Step 1 Draw cross at North side of compass 9 of 18 Step 2 Put compass on cross (drawn) Another cross on north of compass 10 of 18 Step 3 Continue until magnetic field lines are complete 11 of 18 Step 4 Join all crosses 12 of 18 Another way of finding magnetic field Iron filings on piece of card and a bar magnet 13 of 18 Em waves Are transverse waves 14 of 18 Purpose of transverse waves Transfers energy from source to absorber 15 of 18 Red end of spectrum has? low frequency and longer wavelength 16 of 18 Violet end of spectrum has? High frequency and short wavelength 17 of 18 Em waves do not need? a medium to travel in 18 of 18
