Appealing points from the creator
Here are some practical examples of how AR content is used in the classroom. There are two ways of utilization.
One is to "use" the contents created by the teacher, and the other is for the students to "create" their own AR contents.
In this article, we explain how to use the three types of content created by teachers with respect to motor rotation.

【Development1】 Magnetic field of magnet
Predict the direction of a directional magnet when placed around a bar magnet and then submit
Sprinkle iron powder around a bar magnet, observe the magnetic field lines, and submit a photograph
Take the AR magnet out from the material box and observe it in three dimensions
【Development2】Magnetic field due to electric current
Pass an electric current through a straight and coiled conductor, respectively
Place a compass needle around the conductors and observe the direction of the magnetic field
【Development3】Electric current and magnetic field and force
Place a compass needle around the U-shaped magnet
Write down the direction of the magnetic field lines and submit
Assemble an electric swing and conduct experiment to see which direction the conductors move when you change the direction of the current or magnetic field
Take pictures, organize and submit the results of your experiment
【Development4】Making of Clip motor
Watch the movie of how to make clip motors in the resource box and then make one clip motor per person.
Take a video of it spinning for at least 10 seconds and submit it
If it spins for more than 10 seconds, it passes the test.
【Development5】Think of a reason to keep turning
Take the AR motor out of the reference box and observe it in three dimensions.
Think about why it keeps turning and explain to each other in pairs
Organize your ideas again and submit them
Listen to the class presentation and resubmit
【Development6】 Move the linear motor
Predict which direction the aluminum pipe will move and move it with a hand-cranked generator
Observe the direction of movement while changing the direction of the current with AR.
