If an electric wire is allowed to produce a magnetic field no larger than that of the earth (0.503 x 104 t) at a distance of 15 cm from the wire, what is the maximum current the wire can carry?

37.725 A

Explanation:

B = magnitude of the magnetic field produced by the electric wire = 0.503 x 10⁻⁴ T

r = distance from the wire where the magnetic field is noted = 15 cm = 0.15 m

i = magnitude of current flowing through the wire = ?

Magnetic field by a long wire is given as

Inserting the values

i = 37.725 A

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
