Streams are a crucial part of Earth's circulatory system. They carry sediments, nutrients and other materials into rivers and lakes and on to the ocean. But streams are also vital ecosystems on their own, providing wildlife habitat, protecting us from floods and supplying much of our drinking water.
Answer: 2400A
Explanation:
magnetic field of a solenoid is given by
B=μ0NIL
and the current is
I=BLμ0N.
N is the length of the wire, divided by the diameter of the wire -
that's how many times you can wind the coils together for a given length.
Therefore,,
there are
N= 1.8/0.002 = 900 turns of the wire. Thus,
I=BLμ0N=1.5×1.84π×10-7×900= 2400 A.
