What Is The Magnetic Flux Density When The Vector Potential Is A Position Vector? Explanation: The field intensity H = -Grad(V). Since the given potential is a position vector, the gradient will be 3 and H = -3. Thus the flux density B = μH = 4π x 10– 7 x (-3) = -12π x
What Is The Magnetic Field Due To An Infinite Linear Current Carrying Conductor? Magnetic field due to an infinitely long straight current carrying wire – definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current. What
What Is The Magnetic Field In The Center Of The Solenoid? For the first part, since the solenoid is long we can approximate the magnetic field inside to be uniform and is given by Bz=μ0NI, so we can say that the magnetic field at the center is also μ0NI. What is the magnetic field at
What Is The Nature Of The Force Between Two Parallel Current Carrying Wires In Same Direction? Thus, when two parallel wires carry current in the same direction, they exert equal and opposite attractive forces on each other. What is the force between two parallel wires? The official definition of the ampere is: One ampere of
What Is The Relation Between Field And Potential? The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the
What Is The Hall EMF? The Hall effect is the creation of voltage ε, known as the Hall emf, across a current-carrying conductor by a magnetic field. The Hall emf is given by. ε = Blv (B, v, and l, mutually perpendicular) for a conductor of width l through which charges move at a speed
What Is The Direction Of The Force On The Wire In The Magnetic Field Produced By The Magnets? The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). What is the direction of the force
How Does Magnetic Field Affect Voltage? Then the action of moving a coil or loop of wire through a magnetic field induces a voltage in the coil with the magnitude of this induced voltage being proportional to the speed or velocity of the movement. Do magnetic fields affect electricity? Electricity and magnetism are two related
How Does Magnetic Field Protect Us? The magnetic field of the Earth plays a very important role in our lives, it protects us from the solar winds. These are currents of particles charged of energy emanated from the sun which emit radiation. … The magnetosphere deflects the dangerous ultraviolet rays of the sun, keeping us
What Is The Formula Of Magnetic Field At The Centre Of Current Carrying Coil? Magnetic Field at the Center of a Circular Current-Carrying Coil. dB = μ 0 4 π Id l sin θ r 2 where is the angle between d l → and . What happens to magnetic field at the centre
