how many turns of solenoid is required to produce a magnetic field having magnitude of 3.0 T upon application of 600A current if the solenoid is 8.50 m long and is having 4500 turns. ( \mu _(0)=4\pi x10^(-7)T. m/A).

what is the magnitude of a magnetic field produced by a 6.50 m long solenoid and is having 3500 turns if a 555A current is applied on it? (note:  \mu _(0)=4\pi x10^(-7)T. m/A).

determine the distance from a long straight wire that would produce a Magnetic Field three times that of the Earth's own field upon the application of 60.0 Ampere currents. (assuming that Earth's Magnetic Field is equal to 5x10^(-5)T and \mu _(0)=4\pi x10^(-7)T. m/A).

determine the Current in a long straight wire that would produce a magnetic field that produces a Magnetic Field four times that of Earth's Magnetic Field located at a distance 9.0 cm from the wire. (assuming that the Earth's Magnetic Field is equal to 5x10^(-5)T and \mu _(0)=4\pi x10^(-7)T. m/A).

Barium ion with a 2+ charge travels at a speed 800 m/s and is acted upon by a magnetic force having a magnitude of 1700.0 N. Determine the magnitude of magnetic field acting perpendicularly on Ba^(2+).

Barium ion with a 2+ charge travel at a speed 800 m/s is moving perpendicular to the magnetic field with a magnitude of 2.0 T. Determine the magnitude of magnetic force acting on Ba^(2+).

determine the kinetic energy of a 125kg roller coaster that is moving with a speed of 20.0 m/s

A beam of particles strikes a wall containing 2x10^29 nuclei per m^3. Each nucleus behaves like a sphere of radius 3x10^−15 m. Find the thickness of a wall that exactly half the particles will penetrate without scattering. What thickness would be needed to stop all but one particle in 10^6 ?

An unmanned vehicle follows a curved path, beginning at O and ending at A, of length 18 m. At O the speed of the vehicle is 12 m/s and it has slowed to 6 m/s at A. The tangential deceleration of the vehicle is proportional to the distance from O. a) Write an equation for tangential acceleration. b) Find the constant of proportionality in your equation
