Open Right Hand Rule Practice

  1. A current travels from your right to your left. A B-field travels from in front of you to behind you. What is the direction of the force?
  2. A current is traveling from in front of you to behind you. A force pushes a wire to your right. What is the direction of the magnetic field?
  3. A current is traveling from over your head to your feet. The B-field is traveling from in front of you to behind you. What is the direction of the force on the current carrying wire?
  4. A current travels from your left to your right. The B-field travels from your right to your left. What is the direction of the force on the wire?
  5. A flow of positive ions travel your left to your right. The north pole of a magnet is over your head and the south pole is at your feet. What is the direction of the force on the flow of charge?
  6. A flow of electrons travel from in front of you to behind you. A force pushes the flow of charge over your head. What is the in front of you pole of the magnetic field?
  7. A flow of electrons travel from in front of you to behind you. A force pushes the wire behind you. Where is the south pole of the magnetic field?
  8. A flow of positive ions travels from in front of you to behind you. The south pole of a magnet is to the your right and the north pole of a magnet is to the your left. What direction is the force that pushes the flow of charged particles?
  9. Electrons flow from your right to your left. They feel a force pulling them to the behind you. Where is the north pole of magnet that creates the external magnetic field?
  10. Electrons flow from in front of you to behind you. The magnetic field points from your feet to over your head. Which direction is the force pointing?
  11. The positive terminal of as battery is to your right. The negative terminal is to your left. When this battery is turned on, charge will flow by in front of you. The current carrying wire feels a force pushing it over your head. Where is the south pole of hte magnet creating the magnetic field?
  12. The positive terminal of as battery is above you. The negative terminal is at your feet. When this battery is turned on, charge will flow by in front of you. The magnetic field points from your right to your left. Which direction is the force pointing?
