The law of Biot-Savart shows that the magnetic field due to an infinitesimally small current element drops of with the square of the distance from the from the current element (1/r^2). Is it possible to put together a complete circuit whose magnetic field exhibits the same type of decrease? Why or why not?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
