Question

1. the electron theory of magnetism theorizes that the magnetic properties of a material can be explained through the electron spin patterns. electrons spinning in the opposite direction add to, and spinning in the same direction will cancel out, the magnetic fields.

true

false

Explanation:

Analyze the electron theory of magnetism

Using the Electromagnetism knowledge point
The electron theory of magnetism states that the magnetic properties of a material are primarily due to the spin and orbital motion of its electrons. An electron acts as a tiny electromagnet because of its spin.

Evaluate the spin alignment statement

Using the Electromagnetism knowledge point

• Electrons spinning in the same direction produce magnetic fields that point in the same direction, which add to (reinforce) each other.
• Electrons spinning in opposite directions produce opposing magnetic fields that cancel out each other.
• The statement in the question asserts the exact opposite: that opposite spins add and same spins cancel. Therefore, the statement is false.

Answer:

• True
• False (Correct answer)
