WebSo does the bulb light up when there's a changing magnetic field because: a moving electromagnetic field will exert a force on the free electrons of a wire to move; moving electrons is the definition of current; thus the bulb lights up. The force applied depends on the direction of the changing magnetic field, thus changing the way current flows. WebResistance in a Wire - PhET

WebThis law enables us to calculate the magnitude and direction of the magnetic field produced by a current in a wire. The Biot-Savart law states that at any point P ( Figure 12.2 ), the magnetic field d →B d B → due to an element d →l d l → of a current-carrying wire is given by. d →B = μ0 4π Id→l ×^r r2. d B → = μ 0 4 π I d l ...

Webthe PhET Circuit Construction Kit does not have an ohmmeter, we will build one. A device designed to have a consistent resistance is a resistor. A conductive wire is a low-resistance resistor. Insulators like rubber and plastic have high resistance. A variable-resistance resistor is called a rheostat or potentiometer. We will build a simple ... WebJan 20, 2015 · Construction Kit (DC Only) simulation at the PhET site. • Make the light bulbs have different resistance values (right click on the bulb to adjust) and record the value of each light bulb in the table below. • Change the voltage of the battery to a value that makes sense for your circuit. WebJun 11, 2014 · 1. Run the PhET sim, “Faraday’s Electromagnetic Lab .” Maximize the window. Click the Pickup Coil tab. You should see a bar magnet, a compass needle grid, and a coil attached to a light bulb. 2. Describe the most effective way of using the magnet and the coil to light the bulb if a. the coil cannot be moved. Move the magnet in and out of the coil. bob mccreary wake forest
