Physics Help! A 0.75 m-long solenoid consisting of 1200 turns is used to generate a magnetic field 0.30 T. How?
A 0.75 m-long solenoid consisting of 1200 turns is used to generate a magnetic field 0.30 T. How much current is required?
Please show work! Thank you!

B = muo x n x i
=> i = B/muo n where muo = 4pi x 10^-7; n = no. of turns per unit length; B = magnetic field induction
i = 0.30/(4pix10^-7x1200/0.75)
=> i = 149.2A

Earth's magnetic field blocks (on an identical time with the ozone layer) risky radiation from attaining Earth's floor. If our megnatic field have been to without be conscious disappear, Earth's floor and oceans could be flooded with risky rays. the outcomes could be widescale optimal cancers and death of vegetation.
