In an MRI, the magnetic field B is generated by a solenoid of length 100 cm and diameter of 90 cm. The B field generated is one
1 answer:
Given,
L=100 cm=0.1 m
D=90 cm
B=1 T
I=76 A
B*L=μnI
1 *0.1= 4π**n*76
n= 1047
So the turns of solenoid needed is 1047.
<h3>Solenoid </h3>A solenoid with infinite length but finite diameter is said to be infinite. In this abstraction, the solenoid is frequently seen as a cylindrical sheet of conductive material. The term "continuous" refers to the fact that the solenoid is not made up of discrete coils with finite widths but rather numerous infinitely thin coils joined together without any gaps. An indefinitely long solenoid has a homogenous magnetic field inside of it that is independent of the cross-sectional area or the distance from the axis. This is a long enough derivation of the magnetic flux density surrounding a solenoid that fringe effects may be disregarded.
In an MRI, the magnetic field B is generated by a solenoid of length 100 cm and diameter of 90 cm. The B field generated is one (1) T. The largest current the wire can carry is 76 A. 1047 turns of solenoid is needed.

Since kinetic energy is a form of energy using the equation KE=¹/₂mv², the units of measurement is in Joules (J). Therefore, the tennis ball had more kinetic energy than the baseball since velocity is a larger factor than the mass is when determining kinetic energy.
