Acircular loop with 30 turns and area of 0.25 m2 rotates at 100 rad/s. the axis of rotation of the loop is perpendicular to the direction of the magnetic field of 0.04 tesla. what is the maximum emf induced in the loop?

e = 30 V

Explanation:

given,

N = 30 turns

Area = 0.25 m²

angular speed = ω = 100 rad/s

Magnetic field = 0.04 T

maximum induced emf in the loop = ?

e = N B A ω

e = 30 x 0.04 x 0.25 x 100

e = 30 V

hence, the maximum emf induced in the loop is equal to e = 30 V

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
