A transmission line strung 5 m above the ground carries a current of 400 A. What is the magnetic field on the ground directly below the wire? Hint Review Section 12.2 Magnetic Field Due to a Thin Straight Wire, where a formula for magnetic field due to a current in a long, thin, straight wire is derived. Watch the units and powers of 10. Magnetic field due to the transmission line is 0.64 x mT. For comparison, the geomagnetic field is around 0.05 mT (varies by latitude). Does the transmission line cianificantly offoct the mggnotic fiold in the oreg no gr it?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
