5. (a) A conducting loop in the shape of a square of M edge length { = 0.400 m carries a current-I = 10.0 A
as shown in Figure P30.5.- Calculate the magnitude
and direction of the magnetic field at-the-center of
the square. (b) What If?. If this conductor is reshaped
to form a circular loop and carries the same current,
what is the value of the magnetic field at the center?​

the assestment will probley apele with cause and effect

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
