You have learned that a charge moving in an magnetic field can experience a magnetic force. Remarkably, anytime that a charged particle moves that particle produces its own magnetic field! The image below of magnetic compasses forming a circle around a current-carrying wire demonstrates the shape of the magnetic field. The magnetic field lines forms concentric circles around that wire. The strength of the field decreases with increasing distance away from the wire. If the current in the wire is 4.07A, what is the magnitude of the magnitude of the magnetic field (in µT, or micro-Tesla) a distance of 0.53m away from the wir Note: It is understood that the unit of your answer is in uT, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

Please help me with this question, thank you so much A straight wire of length A carries a current I. The wire lies along the x-axis. a. Calculate the magnetic field due to the wire of length A at some distance D along the y-axis. b.  Find B, when A>>>>D (One end of the wire is at the origin o and the other is along the x-axis a distance A from the origin)

Two long, parallel wires separated by 80 cm each carry currents of 2.0 A in a horizontal direction. Part A Part complete Find the magnetic field midway between the wires if the currents are in the same direction. Express your answer using two significant figures.   Part B Find if they are in opposite directions. Express your answer using two significant figures.

Two circular loops of wire lie in the x-y plane, centered at the origin. The radius of the loops is 5.00 and 7.00 cm. The current in the outer loop is 50.0 mA in the clockwise direction. a. If the current in the inner wire is also 50.0 mA in the clockwise direction, what is the magnetic field strength at the origin? b. What current magnitude and direction in the inner wire will cause the magnetic field to be zero at the origin?

A thin conducting wire is bent into the shape shown in the figure. The circular portion of the wire has radius 25.0 cm. The wire is in the plane of the screen and carries a current 1.10 A.

Consider the figure shown with current 1 = 3.0 A and current 2 = 1 A.   What is the magnetic field strength at wire segment b due to current 1 if the distance between the wires is L=3.0 cm Draw the magnetic field from wire 1 and show the direction of this field at segment b.  b. What is the resulting force magnitude and direction on wire segment b ( b= 6.0 cm) due to the interaction of current 2 and the magnetic field of current 1? Justify your answer.
