A circular loop of radius 11.9 cm is placed in a uniform magnetic field. (a) If the field is directed perpendicular to the plane of the loop and the magnetic flux through the loop is 8.60 ✕ 10−3 T · m2, what is the strength of the magnetic field? T (b) If the magnetic field is directed parallel to the plane of the loop, what is the magnetic flux through the loop? T · m2

(a). The strength of the magnetic field is 0.1933 T.

(b). The magnetic flux through the loop is zero.

Explanation:

Given that,

Radius = 11.9 cm

Magnetic flux

(a). We need to calculate the strength of the magnetic field

Using formula of magnetic flux

Put the value into the formula

(b). If the magnetic field is directed parallel to the plane of the loop,

We need to calculate the magnetic flux through the loop

Using formula of flux

Here,

Hence, (a). The strength of the magnetic field is 0.1933 T.

(b). The magnetic flux through the loop is zero.

what type of charge does it have? negative

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
