When you get down to that scale, physical size doesnt mean much. But we do know that its mass is much less than the mass of the proton. It takes about 1840 electrons to have the same mass as one proton. The charges on the electron and proton are equal and opposite. The charge on the proton is what we call positive charge. The charge on the electron is what we call a negative charge.

A flat loop of wire consisting of a single turn of cross-sectional area 8.20 cm2 is perpendicular to a magnetic field that incre

Answer:

The  induced current is I  =  6.25*10^{-4} \  A

Explanation:

From the question we are told that  

    The number of turns is  N  =  1

     The  cross-sectional area is  A  =  8.20 cm^2  =  8.20 * 10^{-4} \ m^2

    The  initial magnetic field is  B_i  =  0.500 \ T

     The  magnetic field at time =  1.02 s  is  B_t =  2.60 \ T

     The  resistance is  R  = 2.70\  \Omega

The  induced emf is mathematically represented as

       \epsilon  = - N  *   \frac{ d\phi }{dt}

The  negative sign tells us that the induced emf is moving opposite to the change in magnetic flux

      Here  d\phi is the change in magnetic flux which is mathematically represented as

        d \phi  =  dB  *  A

Where  dB  is the change in magnetic field which is mathematically represented as

        dB  =  B_t  - B_i

substituting values

        dB  =   2.60 -  0.500

        dB  =   2.1 \ T

Thus  

      d \phi  =  2.1 * 8.20 *10^{-4}

     d \phi  = 1.722*10^{-3} \ weber

So  

     |\epsilon|  = 1   *   \frac{ 1.722*10^{-3}}{1.02}

     |\epsilon|  = 1.69 *10^{-3} \  V

The  induced current i mathematically represented as

      I  =  \frac{\epsilon}{ R }

  substituting values

       I  =  \frac{1.69*10^{-3}}{ 2.70 }

       I  =  6.25*10^{-4} \  A
