A powerful bolt of lightning can carry a current of 225 kA. (a) Treating a lightning bolt as a long, thin wire, calculate the magnitude of the magnetic field produced by such a bolt of lightning at a distance of 91 m. (Answer in µT) (b) If two such bolts strike simultaneously at a distance of 25 m from each other, what is the magnetic force per meter exerted by one bolt on the other? (Answer in N/m)
In a lightning bolt, a large amount of charge flows during a time of 2.1 10-3 s. Assume that the bolt can be treated as a long, straight line of current. At a perpendicular distance of 30 m from the bolt, a magnetic field of 7.8 10-5 T is measured. How much charge has flowed during the lightning bolt? Ignore the earth's magnetic field.
In a lightning bolt, 12 C of charge flows in a time of 1.5 times 10^-3 s. Assuming that the lightning bolt can be represented as a long, straight line of current, what is the magnitude of the magnetic field at a distance of 26 m from the bolt? 61.53e-12 T
007 10.0 points A bolt of lightning, such as the one shown on the left in the figure, behaves like a vertical wire conducting electric current. As a result, it produces a magnetic field whose strength varies with the distance from the lightning. A 108-turn circular coil with a radius of 0.835 m is oriented perpendicular to the magnetic field as shown. The magnetic field at the coil drops from 4.30 x 10 3 T to 0.00 T in 10.5...
Assume that a lightning bolt can be represented by a long straight line of current. If 15.0 C of charge passes by in a time of 1.5·10-3s, what is the magnitude of the magnetic field at a distance of 22.0 m from the bolt?
A lightning bolt produces a rapidly varying magnetic field. If the bolt strikes the earth vertically and acts like a current in a long straight wire, it will induce a voltage in a loop aligned like that in. What voltage is induced in a 1.00 m diameter loop 25.0 m from a 2.00 x 105 A lightning strike, if the current falls to zero in 100 us? (V) 11.2 0 12.6 13.1 100 130
