Q: A loop that consists of 200 ( N ) turns and an area ( A ) of 0.25 m2 is located in a downward-directed magnetic field ( B ) of 0.40 T. Additionally, the loop’s coils have a resistance ( R ) of 5.0 Ω. If the coils are crushed to an area ofContinue reading “MAGNETISM AND ELECTROMAGNETISM: Lenz’ Law”

MAGNETISM AND ELECTROMAGNETISM: Electromagnetic Induction and the Electromotive Force ( emf )
Q: A metallic coil that consists of 200 ( N ) turns encloses an area ( A ) of 100 cm2. The coil is placed within a magnetic field ( B ) that is perpendicular to its area, and it has a magnetic flux density of 0.50 T. Next, the field is shut off, andContinue reading “MAGNETISM AND ELECTROMAGNETISM: Electromagnetic Induction and the Electromotive Force ( emf )”
MAGNETISM AND ELECTROMAGNETISM: Magnetism, Electromagnetic Induction, Lenz’s Law, and the Right-Hand Rule
Early experiments with magnetism revealed that a current-carrying wire is surrounded by circular lines of magnetic flux ( ɸ ). The orientation of this field could be predicted via usage of the Right-Hand Rule. These observations are indeed interesting, and they were made when the current ( I ) passing through a conductor was constant;Continue reading “MAGNETISM AND ELECTROMAGNETISM: Magnetism, Electromagnetic Induction, Lenz’s Law, and the Right-Hand Rule”
INTRODUCTION TO ELECTRONICS: Power in Series Circuits
Thus far, we have seen how the net resistance ( R ) to current ( I ) flow within a series circuit is the sum of all the resistors that are present: Rt = R1 + R2 + R3 +…Rn The voltage ( V ) drop that occurs as a coulomb ( C ) ofContinue reading “INTRODUCTION TO ELECTRONICS: Power in Series Circuits“
