5/6 pts Question 8 An infinite wire and an infinite length conductor sheet are carrying currents 11 and 12, respectively. Both are placed parallel to the the z axis with the wire coinciding with the z axis. The conductor sheet has a semi-circle cross-section with radius b and negligible thickness. Derive an expression for the unit-length force acting on the conductor sheet due to the current passing in the wire. Current / out of the paper Currentl2 into the paper...
Part D Constants Long, straight conductors with square cross section, each carrying current I, are laid side-by-side to form an infinite current sheet with current directed out of the plane of the page (see the figure (Figure 1)). A second infinite current sheet is a distance d below the first and is parallel to it. The second sheet carries current into the plane of the page. Each sheet has n conductors per unit length. Find the direction of the net...
4. A vertical straight wire carrying an upward 28 A current exerts an attractive force per unit length of 7.8x10-4 N/m on a second parallel wire 9 cm away. What current (magnitude and direction) flows in the second wire?
please do both of them asap
4) A wire is carrying a current of I and it is placed in a magnetic field of B, the force on the wire is zero if: A) The length of wire is infinite. B) If there is a non-zero angle between magnetic field B and current I. C) The direction of the current and magnetic field are perpendicular. D) The current and magnetic field are parallel. E) There is a 90 degree angle...

A physics instructor performs a demonstration where a current-carrying wire is made to levitate. The wire has a mass per unit length of 0.590 g/cm and carries a current of 2.06 A horizontally to the south. Find the magnitude and direction of the minimum magnetic field needed to lift this wire vertically upward. (Enter the magnitude in T.) Magnitude:? Direction:?
4. A thin wire carrying a current I is bent into a shape with a central circular portion of radius R centered at the origin, and with two semi-infinite arms that extend to ro, as shown in the figure below. Find the direction and the magnitude of the magnetic field B at the center. y R I
2) A very large number of very long wires are arranged to form a current-carrying “ribbon," as shown in the figure below. Each wire can be assumed to have negligible radius and carries the same current I (in the same direction). The ribbon is oriented in the xy-plane, at z =0. Hint: This problem has planar symmetry, so consider how you might apply Ampere's Law. Also note that this problem is equivalent to an infinite current-carrying sheet with surface a...
Two insulated current-carrying wires (wire 1 and wire 2) are bound together with wire ties to form a two-wire unit. The wires are 2.95 m long and are stretched out horizontally parallel to each other. Wire 1 carries a current of I, = 8.00 A and the other wire carries a current I, in the opposite direction. The two-wire unit is placed in a uniform magnetic field of magnitude 0.400 T such that the angle between the direction of I,...
