When teaching magnetism, hands-on learning opportunities enable students to observe and engage with magnetism and magnetic fields principles. By experimenting with magnets, we want our students to understand the concept of magnetic po...
Magnets 11-13 having the prescribed polarity are so contained in a stationary unit 7 opposed to the gear 6 to attract or repel the pin 9, the inermittent rotary force is transmitted from the gear 6 to the rotor 5 by telescoping the pin 9, and a nonmagnetic thin unit 15 is interposed...
