Suppose you have two wires placed horizontally. lets say the first carries a current l1=90A. The second is placed 25cm below the first one. if the lower wire has a mass of 0.15 grams per meter of length, how much current,if possible, this second wire has to carry if we don't want it ti fail by gravity?

Two wires are located at the distance d=4m as shown in the diagram. y d/2 #1 #2 d/2 A d/2 d/2 B Wire #1 carries a current of 4 A in the shown direction. Wire #2 carries a current of 2 A in the shown direction. Hol Units: Tesla (T) B = 2nr' Ho=47tx10-7 T*m/A 1. Find the magnitude and direction of total magnetic field at point A, located exactly in the middle between two wires. 2. Find the magnitude and direction of total magnetic field at point B, located at the distance d/2 to the right of wire #2 as shown in diagram. 3. Find the magnitude of total magnetic field at point C, located at the distance d/2 above the point A as shown in diagram. 4. Find the direction (angle related to positive +x axis) of total magnetic field at point C, located at the distance d/2 above the point A as shown in diagram.

Two 44 meter long parallel wires experience an attractive force of 0.0006 N. If they are 0.42 m apart and I1=10A, find the current in the other wire.

Two parallel wires separated by 4.25 cm repel each other with a force per unit length of 1.90 x 1o-4 N/m. The current in one wire is 5.30 A. (a) Find the current in the other wire. A (b) Are the currents in the same direction or in opposite directions? O the same direction O opposite directions (c) What would happen if the direction of one current were reversed and doubled?

Final Answer must be whole number or decimal number only!!!

a proton (mass 1.67e-27 kg, charge 1.6e-19) with a constant speed of 3.1 x 10^4 is traveling in a vacuum chamber at a distance 1.90 cm above a long horizontal wire that carries a current I. It moves in a direction to the wire (opposite the current). Determine the value of I

Two straight parallel wires are separated by 7.5 cm. There is a 2.0-A current flowing in the first wire.

Suppose in the figure that the four identical currents i = 14 A, into or out of the page as shown, form a square of side 70 cm. What is the force per unit length (magnitude and direction) on the wire in the bottom left hand corner? (N/m) Take the positive y direction as up and the positive x direction as to the right.What is the magnitude of the force per unit length? Check the units for MKS.   Incorrect. Tries 2/4 Previous Tries What is the x component of the force per unit length?   Tries 0/4   What is the y component of the force per unit length?   Tries 0/4

The unit of surface current is A/m^2. Select one: True O False

A cylindrical wire carries a steady current density modeled as J(r) = Cr², where ris radial distance from 1.5 mm. If 15.0 C of charge flows through the wire in 5.0 s, center of the wire. The radius of the wire is R determine C.
