Question
The figure on the right shows that two very long current carrying conductor. The currents on the carries 1.0A and 4.0A on the left and right respectively. The separation between them is 10 0 cm What is the magnetic field produced by h in between the two currents? What is the total magnetic field in the middle considering the contribution of both current? What is the direction of the net magnetic field? Now a proton is traveling from S to N in between the two currents at a speed 10 times 107 m/s. What is the force experienced by the charge? In what direction? The charge of proton is 1.6 times 10-19C. Next, what is the magnetic field produced by 1.10 cm away, on the I2? Use the result above, find out the forces per unit length acting on the I2 as a result of interacting with field produced by I2? And in what direction? Somewhere between the currents or outside the field produced by the 2 currents cancel out each other. Where will that be?Explanation / Answer
are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. The interaction of magnetic field with charge leads to many practical applications. Magnetic field sources are essentially dipolar in nature, having a north and south magnetic pole. The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).
