As a new electrical technician, you are designing a large solenoid to produce a uniform 0.150-t magnetic field near the center of the solenoid. you have enough wire for 3100 circular turns. this solenoid must be 57.0 cm long and 7.00 cm in diameter. what current will you need to produce the necessary field?

I = 21.94 A

Explanation:

Given that

B= 0.15 T

Number of turns N= 3100

Length L = 57 cm

Diameter ,d= 7 cm

We know that magnetic field in the solenoid given as

Now by putting the values

I = 21.94 A

Therefore current need to produce 0.15 T magnetic filed is 21.94 A.

correct it is c.) b b

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
