Question

Identify the false statement regarding magnetic properties of substance.
(A) Paramagnetic substances are weakly attracted.
(B) Diamagnetic substances are weakly attracted.
(C) Ferromagnetic substances strongly attracted.
(D) Diamagnetic substance strongly attracted

• A. (A) and (C) only
• B. (A), (B), (C) and (D)
• C. (B) and (D) only
• D. (A) and (B) only

Hint:

Diamagnetic substances are weakly repelled, not attracted.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Substances respond to a magnetic field in three main ways. Paramagnetic ones are weakly attracted, diamagnetic ones are weakly repelled, and ferromagnetic ones are strongly attracted.

Step 2: Check statement (A)
Paramagnetic substances have unpaired electrons and are weakly attracted. So (A) is TRUE.

Step 3: Check statement (B)
Diamagnetic substances are weakly repelled by a field, not attracted. So (B) is FALSE.

Step 4: Check statement (C)
Ferromagnetic substances such as iron are strongly attracted. So (C) is TRUE.

Step 5: Check statement (D)
Diamagnetic substances are not strongly attracted; they are weakly repelled. So (D) is FALSE.

Final Answer:
The false statements are (B) and (D) only, option (C). \[ \boxed{\text{(B) and (D) only}} \]
