What do you mean? You can't just "remove" the negative sign. As Dadface says, that negative sign in Faraday's law is called Lenz's law. Read about it here: http://hyperphysics.phy-astr.gsu.edu/HBASE/electric/farlaw.html#c2"waqarrashid33 said:if the -ve sighn is removed then what will be done with this law?
For one thing, energy will not be conserved--you'll have a source of "free" energy.waqarrashid33 said:i mean that if we assume that lenz's law is wrong then what will happen?
Then we get a contradiction between what the law says and what is actually observed.waqarrashid33 said:i mean that if we assume that lenz's law is wrong then what will happen?
The negative sign in Faraday's law of electromagnetic induction represents the direction of the induced electromotive force (EMF) or voltage. It indicates that the induced EMF creates a current that opposes the change in magnetic flux, according to Lenz's law.
The negative sign in Faraday's law means that the induced EMF has a direction opposite to the change in magnetic flux. This direction is important in determining the magnitude and direction of the induced EMF and current in a given circuit.
Yes, Faraday's law can be used to determine the direction of the induced current in a circuit. The negative sign in the equation indicates the direction of the induced current, which is opposite to the change in magnetic flux.
The negative sign in Faraday's law is crucial in understanding the direction of the induced EMF and current in a circuit. It helps us predict the behavior of electromagnetic systems and design circuits that utilize electromagnetic induction.
No, the negative sign in Faraday's law does not always indicate an opposing current. In some cases, the induced current may be in the same direction as the change in magnetic flux, resulting in a positive value for the induced EMF. This is known as mutual induction and is commonly seen in transformers.
