Question

7 in what way are magnetic fields and electric fields similar?
a they can give objects electric charge
b they can cause objects to move without touching them
c they can remove an object’s charge
d they can prevent charged objects from moving

Explanation:

• Option A: Magnetic fields don't give electric charge; electric fields act on existing charges. Eliminate A.
• Option B: Electric fields exert force on charged objects, magnetic fields on moving charged objects or magnets—both can move objects without contact. This fits.
• Option C: Neither field removes an object’s charge. Eliminate C.
• Option D: Fields cause motion (or force), not prevent it. Eliminate D.

Answer:

B. They can cause objects to move without touching them
