When the current in a coil is halved, the magnetic field strength generated by the coil is also halved, following the equation B = μ₀ * n * I, where B is the magnetic field strength, μ₀ is the permeability of free space, n is the number of turns in the coil, and I is the current. This decrease in magnetic field strength will also affect any nearby magnetic materials, potentially reducing the overall magnetic flux and induced voltage in any nearby circuits or devices. Additionally, the force experienced by the coil in a magnetic field, as described by the Lorentz force law, will also be reduced proportionally to the decrease in current.
What else can I help you with?
Why the current coil of wattmeter has more thikness wire than pressure coil?
Current coil carries the current.
What happens to the current in a circuit if one resistance is doubled or halved?
P1 = V I1, Therefore, if P2=0.5*P1, thenI2=0.5*P1/V, or 0.5*I1and if P3=2*P1, thenI3=2*P1/V, or 2*I1In other words, current is proportional to power and inversely proportional to voltage.
What happens when a coil of wire cuts through a magnetic field?
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire. If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.
What is current coil and voltage coil?
Oh, dude, current coils and voltage coils are just like the Beyoncé and Jay-Z of transformers. The current coil measures the current flowing through a circuit, while the voltage coil measures the voltage across a circuit. They're basically the dynamic duo of electrical measurements, keeping things in check and making sure everything runs smoothly.
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
What happens to the electric current if the magnet no longer moves in the coil?
The electrical current stops flowing.
Why current becomes halved when load is halved in transformer?
Load halved means the power is halved.Voltage being (assumed) constant, the current is halved. P (Load in Watts)= V x I Hence P/2= V x I/2
What happens to the circumference if the diameter is halved?
Yes it does. By a factor of 4.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens when you multiply a number by 0.5?
It is halved.
What happens to the resistance when length is doubled n area is quadrupled?
It is halved.It is halved.It is halved.It is halved.
What happens to pressure when the temperature and volume is halved?
if kelvin temp is halved, the volume is halved if pressure is constant.
If you double the volume of an object what happens to the density?
It is halved.
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
What happens when electric current passes through a coil of wire?
When electric current passes through a coil of wire, a magnetic field is generated around the coil. This phenomenon is known as electromagnetic induction. The strength of the magnetic field is directly proportional to the amount of current flowing through the coil.
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
