For this learning task, you will determine the shape and direction of the magnetic field surrounding a bar magnet, horseshoe magnet, straight conductor, and solenoid using an interactive simulation.
Select the bar magnet, horseshoe magnet, straight conductor, or solenoid to work with.
Draw a diagram of the object you are working with.
Place the compass in a location around the object and record the direction of the magnetic field on your diagram.
Repeat step 3 as necessary so that you have a complete picture of the shape and direction of the magnetic field surrounding the object.
Repeat steps 2-4 for the other three objects.
Once you have created the four diagrams, create two more that use the right hand rules to determine the direction of the magnetic field surrounding the straight conductor and solenoid if the current flow were to be reversed.
