Ampere's law states that the magnetic field around a closed loop is directly proportional to the current passing through the loop. For a current loop, Ampere's law can be used to calculate the magnetic field strength at any point around the loop.
Ampere's law states that the magnetic field around a closed loop is directly proportional to the current passing through the loop. This law is used to calculate the magnetic field strength around a current-carrying wire by integrating the magnetic field along a closed loop surrounding the wire.
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
The induced current in a loop is directly affected by changes in magnetic field strength. When the magnetic field strength increases or decreases, it causes a change in the magnetic flux passing through the loop, which in turn induces an electric current in the loop according to Faraday's law of electromagnetic induction.
Increasing the strength of the magnetic field passing through the loop, increasing the number of turns in the wire loop, or increasing the speed at which the magnetic field changes can all increase the current in a stationary wire loop through Faraday's law of electromagnetic induction.

Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
Convert the current to amperes, then (using Ohm's Law), divide voltage by current.
Six, Voltage is the same in a parallel circuit but current divides to total the sum of each branch. See Kirchoffs current law.
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
Ohm's Law: Voltage is resistance time current So, 28 ohms and 3.8 amperes means 106.4 volts.
3 amperes. Ohm's law: Voltage is ohms times amperes.
Ohm's law states that the resistance of current between two points is proportional to the potential difference. R = V / I R is resistance in Ohm's, V is potential in Voltage and I is current in Amperes.
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
