PHYS 2240 Lab Report 2(Lab 9, Magnetic Field in a Current Carrying Coil) INTRODUCTIONIn the experiment, the current-carrying coil’s radial and axial magnetic fields are plotted against Magnetic Field Sensor position passing through the coil. These attractive fields are plotted analytically to a short solenoid by means of the Electronics Laboratory that is approximated by the use of equations for the magnetic field of a particular coil and the magnetic field of a long solenoid equation.HYPOTHESISSINGLE COILA resistor is an apparatus that repel an electric current through it and generally it is bound to Ohm’s Law. Resistors are connected in series, in parallel or in a series parallel arrangement. A solitary resistor that can replace a complicated series parallel circuit to produce the same resistance is a corresponding resistor. The corresponding resistor produces similar current as the original series parallel circuit as long as both systems get the same voltage.In series circuit, the individual resistances are added to compute the subsequent resistance, as in Equation 1. In parallel circuit, the shared individual resistances are added to estimate the shared equivalent resistance as in Equation 2, which we can then invert to find the true equivalent resistance. Equivalent resistance for progressively complicated series parallel circuits is estimated by combining and shifting the two equations.Equation1Req=R1+R2−Resistance of a Series CircuitReq-the equivalent resistance2

It states that the electric potential difference linking two points (V) corresponds to the result of the current connecting the two points (I) and the overall resistance of the system (R). Equation 3 V=IR −Ohm’s LawV is the voltage (or the electric potential difference), I is the current, and R is the resistance.We use a modified form of Ohm’s Law to solve for the total resistance of the system (R), resistance from the recognized voltage and the experimented current.
