Question

Electric and Magnetic Field Lines:

a. Similarity 1: Both exhibit inverse square law behavior.
b. Similarity 2: Both obey the laws of vector addition.
c. Difference 1: Electric field lines begin and end on charges, while magnetic field lines are always closed loops.
d. Difference 2: Electric field lines are influenced by the presence of charges, whereas magnetic field lines are influenced by moving charges (currents).

Answer 1

Electric and magnetic field lines have similarities and differences. They both exhibit inverse square law behavior and obey the laws of vector addition. However, electric field lines begin and end on charges, while magnetic field lines form closed loops.

Step-by-step explanation:

Electric field lines and magnetic field lines have several similarities and differences. Both exhibit inverse square law behavior and obey the laws of vector addition. However, one key difference is that electric field lines begin and end on charges, while magnetic field lines form closed loops. Another difference is that electric field lines are influenced by the presence of charges, whereas magnetic field lines are influenced by moving charges (currents).
