A long solenoid (1,093 turns/m) carries a current of 13 mA and has an inside diameter of 5 cm. A long wire carries a current of 1.9 A along the axis of the solenoid. What is the magnitude of the magnetic field at a point that is inside the solenoid and 1 cm from the wire? Write your answer in micro-tesla.

B= 1.3 ×10 −3T And B= 6.524×10^-4T

Explanation:

Given that,

Length of solenoid = 0.5m

Numbers of turns n=1093 turns/m

n=1093×0.5= 546.5 turns

Current I = 1.9 A

We know that,

Magnetic induction at the axis inside the solenoid

B=μ 0 Ni

B=4π×10 −7 ×546.5×1.9

B= 1.3 ×10 −3T

Now, the magnetic induction at one end on the axis of solenoid

B= μ0Ni/2

B = 4π×10 −7 ×546.5×1.9 /2

B= 6.524×10^-4T

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
