Question and answer
Why will a magnet placed in front of a tele- vision picture tube distort the picture? (Do NOT try this with a color set!) 1. The magnetic field will distort the TV signal. 2. The iron parts in the TV set are magne- tized and thus do not work properly. 3. The magnetic field will magnetize the materials in the TV screen. 4. Moving electrons in the TV set are de- flected from their paths by magnetic field. 5. None of these

Weegy: The answer is: 4. Moving electrons in the TV set are de- flected from their paths by magnetic field.

User: A strong magnet attracts a paper clip to itself with a certain force. Does the paper clip exert a force on the strong magnet? If not, why not? If so, does it exert as much force on the magnet as the magnet exerts on it? 1. No force; the paper clip is not itself a magnet. 2. Equal force; Newton’s third law applies here. 3. It depends on the material in the mag- net. 4. A smaller force; the magnetic field of the paper clip is much weaker than the magnetic field of the strong magnet. 5. None of these

Weegy: 2. Equal force; Newton’s third law applies here

User: Magnet A has twice the magnetic field strength of magnet B (at equal distance) and at a certain distance pulls on magnet B with a force of 47 N. With how much force, then, does magnet B pull on magnet A? Answer in units of N
