The earth's magnetic field, like any magnetic field, stores energy. The maximum strength of the earth's field is about 7.0 10-5 T. Find the maximum magnetic energy stored in the space above a city if the space occupies an area of 7.20 108 m2 and has a height of 800 m.
The earth's magnetic field, like any magnetic field, stores energy. The maximum strength of the earth's field is about 7.0 x 10-5 T. Find the maximum magnetic energy stored in the space above a city if the space occupies an area of 4.9 x 106 m2 and has a height of 1900 m.
Assuming the Earth's magnetic field averages about 0.50×10−4 T near Earth's surface, estimate the total energy stored in this field in the first 10 km above Earth's surface. The radius of Earth is 6380 km.
Compare the electric energy that can be stored in a capacitor to the magnetic energy that can be stored in an inductor of the same size (that is, the same volume). For the capacitor, assume that air is between the plates; the maximum electric field is then the breakdown strength of air, about 3 MV/m. The maximum magnetic field attainable in an ordinary solenoid with an air core is on the order of 10 T. uE /uB = __× 10^__

What is the maximum electric field strength (in kV/m) in an electromagnetic wave that has a maximum magnetic field strength of 5.10 ✕ 10−4 T (about 10 times the Earth's)? kV/m The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 10 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.) m
The orientation of small satellites is often controlled using torque from current-carrying coils in Earth's magnetic field. Suppose a multiturn coil has a cross-sectional area of 6.96 ✕ 10−4 m2, dissipates 0.300 W of electrical power from a 5.50 V power supply, and provides a magnetic moment of magnitude 0.0400 A · m2. (a) Find the coil current I (in A). A (b) Calculate the number of turns in the coil. turns (c) Calculate the maximum magnitude of torque (in...
