Can someone help me with this homework question?

Lines of force do what ?A)are created by electricity onlyB)repelC)never crossD)cancel out magnets

Answer:

What's wrong with your check engine light?
auto zone or a dealer will read your check engine comp and know what is malfunctioning
Find an independent repair shop and have them scan the computer and repair what is needed but stay away from any of those chain stores.
d) they cancel out magnets
1. Magnetic lines of force are continuous and will always form closed loops. 2. Magnetic lines of force will never cross one another. (c) 3. Parallel magnetic lines of force traveling in the same direction repel one another. Parallel magnetic lines of force traveling in opposite directions tend to unite with each other and form into single lines traveling in a direction determined by the magnetic poles creating the lines of force. (B) 4. Magnetic lines of force tend to shorten themselves. Therefore, the magnetic lines of force existing between two unlike poles cause the poles to be pulled together. 5. Magnetic lines of force pass through all materials, both magnetic and nonmagnetic. 6. Magnetic lines of force always enter or leave a magnetic material at right angles to the surface. B and C
