A point charge Q moves on the x-axis in the positive direction with a speed of 280 m/s. A point P is on the y-axis at y = +70 mm. The magnetic field produced at the point P, as the charge moves through the origin, is equal to -0.30 mu T k. What is the charge Q? (mu_0 = 4 pi Times 10^-7 T. m/A). What is the polarity of the charge?
A current I=15A is directed along the positive axis and perpendicular to the magnetic field. A magnetic force per unit length of 0.2 N/m (F/L) acts on the conductor inthe negative y-direction. Calculate the magnitude and direction of the magnetic field in the region through which the current passes.
Learning Goal: To understand how to use the principle of superposition in conjunction with the Biot-Savart (or Ampere's) law.From the Biot-Savart law, it can be calculated that the magnitude of the magnetic field due to a long straight wire is given byB_{rm wire}=frac{mu_0 I}{2pi d} ,where mu_0 (!=!4pi times 10^{-7}; rm T cdot m/A) is the permeability constant, I is the current in the wire, and d is the distance from the wire to the locationat which the magnitude of...
Find the electric field (magnitude and direction as measured from the x axis) at the point P which is located along the x axis at xP = 11.7 m. A finite line of charge with linear charge density lambda = 3.20 Times 10-6 C/m, and length L = 0.896 m is located along the x axis (from x = 0 to x = L). A point charge of q = -7.32 Times 10-7 C is located at the point x0...
D Question 4 1.2 pts 4) A uniform magnetic field is directed in the -z direction. A rectangular wire wound 5 times with a length of 0.7 meters and width of 0.8 meters is placed in the x-y plane in the field. The magnetic field is changed in magnitude from 15 Tesla to 4 Tesla in a time of 0.6 seconds. If the resistance of the wire is 7 Ohms, what is the magnitude and direction of its magnetic moment...
. Find the magnitude and direction of magnetic field produced at point P, by a long wire carrying current of 50 A (running vertical along y-axis)). Point P is 2cm from the wire. having huge problem understanding please breakdown step by step
Earth's magnetic field varies in magnitude and direction from point to point in space. This spatial variation is characterized by the gradient and curvature of the field. Together, the field's gradient and curvature cause charged particles in the plasmasphere to experience a "longitudinal drift", resulting in an orbital motion around the Earth. Use the following formula (instead of textbook eq. 6.64) tau_d=2piqBr^2/3E_k, r=R_E+h, B=B_0(R/r)^3 to calculate the longitudinal drift orbital periods of 10 MeV protons at orbit altitudes of h=500...
