36 the current illustrated in the diagram is directed upward in a straight vertical wire

An object with mass m and charge q is moving vertically downward with speed v when it is at the same vertical position as a horizontal current-carrying wire, as shown above. The current in the wire is directed out of the page. The magnitude of the magnetic field created by the wire at the location of the object is B. depends on its velocity and charge . In the case of a current-carrying wire, many charged particles are simultaneously in motion, so the magnetic force depends on the total current and the length of the wire . The size of the magnetic force on a straight wire of length carrying current in a uniform magnetic field with strength is.

The ratio F/l is the force per unit length between two parallel currents and separated by a distance r.The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and other plasmas. The force exists whether the currents are in wires or not.

The current illustrated in the diagram is directed upward in a straight vertical wire. A compass is placed alongside the wire at the X mark. Which way will - 2166040 Lenz's Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz's law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere. The direction of the current in the conductor (wire) is shown by the central arrow. and they also have a direction indicated by the arrows on the lines. Similar to the situation with electric field lines, the greater the number of lines (or the closer they are together) in an area the stronger the magnetic field.

Model the vortex as a long, straight wire carrying a current. In each of parts (a) through (c) of Figure P30.2, find the direction of the current in the wire that would produce a magnetic field directed as shown. Calculate the magnitude of the magnetic field at a point 25.0 cm from a long, thin conductor carrying a current of 2.00 A. current flows in the counterclockwise direction. The current then sets up an induced magnetic field and produces a positive flux to counteract the change. The situation described here corresponds to that illustrated in Figure 10.1.7(c). Alternatively, the direction of the induced current can also be determined from the point of view of magnetic ...

Use Ampere's Law to derive that inside a wire with a uniform current distribution, B(r) is proportional to r. Recall the case of the electric field E(r) inside a wire with a uniform charge distribution: E(r) is also proportional to r. Outside a long, straight wire, both E and B as proportional to 1/r.
