Magnetic Materials & Curie Law
A thin light weight rod of diamagnetic substance such as silver is suspended in uniform external magnetic field. It will align itself with its length
Show answer and solution
Answer: (b)
- A diamagnetic rod tends to move from stronger to weaker field regions.
- It reduces its energy by keeping as little of its length along the field as possible, so it sets perpendicular to the field.
- So the answer is (b) perpendicular to the magnetic field.
