Two parallel conductors are carrying currents in the samedirection.The currents are nonzero
and not necessarily equal. The magnitude of the magneticfieldmidway between them
is 40 Î¼T. If one of the currents then has its directionreversed,what is the resulting
magnitude of the magnetic field midway between them?
a. a value greater than 40 Î¼T
b. 40 Î¼T
c. a value less than 40 Î¼T

(a) Consider a capacitor with vacuum between its large, closely spaced, oppositely charged parallel plates. Show that the force on one plate can be accounted for by thinking of the electric field between the plates as exerting a "negative pressure" equal to the energy density of the electric field. (b) Consider two infinite plane sheets carrying electric currents in opposite directions with equal linear current densities . Calculate the force per area acting on one sheet due to the magnetic field, of magnitude , created by the other sheet. (c) Calculate the net magnetic field between the sheets and the field outside of the volume between them. (d) Calculate the energy density in the magnetic field between the sheets.

Two long, straight, parallel wires carry currents that are directed perpendicular to the page as shown in Figure P30.9. Wire 1 carries a current I₁, into the page (in the negative z-direction), and passes through the x-axis at x = +α. Wire 2 passes through the x-axis at x = –2a and carries an unknown current I₂. The total magnetic field at the origin due to the current-carrying wires has a magnitude The current I₂ can have either of two possible values, Find the value of with the smaller magnitude, stating it in terms of I₁, and giving its direction.

two very long straight parallel wires carry currents that are directed perpendicular to the page as shown in the figure. Wire 1 carries current I₁ into the page in the negative direction and passes through the x-axis at x=+a. Wire 2 passes through the x-axis at x=-2a and carries an unknown current I₂. The total magnetic field at the origin due to the current-carrying wire has the magnitude The current I₂ can have either of two possible values.
