Answer the following questions about magnetic forces and fields. a) Explain what a magnetic field is (1 mark) b) Explain how you determine the direction of a magnetic field (1 mark) c) Describe two ways you can increase the strength of an electromagnet (1 mark) g. Use the second hand rule to determine the position of the north pole due to the current (e-flow) through each solenoid. Remember the short end of the battery symbol is the negative terminal while the long end is the positive terminal. Current flows from the negative terminal to the positive terminal. a.
