Physics: 1. which is true about the behavior of magnets? a. both like and unlike poles can attract and repel each other depending on the surrounding materials. b. like poles repel each other, and unlike poles attract each other. c. like poles attract each other, and unlike poles repel each other. d. none of the above are true. 2. according to the right-hand rule, if a current-carrying wire is grasped in the right hand with the thumb in the direction of the current, the four fingers will curl in the direction

because his mother is a widow and Jerry an only child, she is protective of her son; likewise, Jerry feels emotionally tied to her. Explanation:...

b.Like poles repel each other, and unlike poles attract each other.

Explanation:

here two opposite poles are showing similar behavior of attraction or repulsion between magnets as that of nature of two opposite charges.

Magnetic field

Explanation:

This is right hand thumb rule according to which the magnetic field will along curl of fingers if thumb is along magnetic field.

d. Both a. and c. are correct.

Explanation:

Magnetic field due to a closed loop is given by

$B = \frac{\mu_0 Ni}{2r}$

so here in order to increase the magnetic field we have to increase the number of loops and current.

d.B is independent of the current in the wire.

Explanation:

As we know that the magnetic due to a wire carrying current is given by

$B = \frac{\mu_0 i}{2\pi r}$

so here we can say that

a.B is proportional to the current in the wire.

b.B is inversely proportional to the distance from the wire.

c.The lines of B form concentric circles about the wire.

so here FALSE statement will be

d.B is independent of the current in the wire.
