What is magnetic field formula? The magnitude of the magnetic field equation is derived from Ampere-Maxwell law. The magnitude of the magnetic field is given by the formula: B=μ0∗I2∗Π∗r, where r is the distance to the wire, I is the electric current, and μ0 is a constan...

I am interested in finding out if there is an equation that you can use to calculate the amount of 'current or voltage' produced in a single copper wire by knowing the 'strength' and 'speed' of a moving permanent magnetic field that is perpendicular to said wire. Application is that of...

Equation 12-4 is correct if the direction of the wire is perpendicular to the field direction. In the event that the direction of the wire makes an angle? with respect to B, we must express the force as (12-5)FM=BIL sin╡ θ Example A straight wire passes...
Magnetic field at the centre of the circle is given by, $B = \dfrac{{{\mu _0}I}}{{2r}}$ Substituting the values in above equation, We will get, $B = \dfrac{{\left( {4\pi \times {{10}^{ - 7}}} \right) \times \left( {1.6 \times {{10}^{ - 19}}} \right)}}{...

Considering the influence of electromagnetic field on the structural deformation,and supposing that the wire's deformation was small,a natural lateral vibrant control equation of wire carrying electric current under the periodical excitation in the magnetic field was established by chord modeling.The criti...
