Who invented the EMF detector?
Michael Faraday is credited with inventing the concept of electromagnetic field detection in the early 19th century, which later led to the development of the EMF detector. The modern EMF detector is a device that can measure electromagnetic fields in the environment, and is commonly used in paranormal investigations and by electricians to detect sources of electromagnetic interference.
What is a device that measures the strength of an electric current?
An ammeter is a device that measures the strength of an electric current. It is usually connected in series with the circuit where the current is to be measured and provides a reading in units of amperes.
A device which provides a continuous record of the humidity?
A hygrometer is a device that measures and provides a continuous record of humidity levels in the air. It typically displays the information on a digital screen or chart for easy monitoring. This is useful in maintaining optimal humidity levels in environments like greenhouses, industrial processes, and storage facilities.
What is the Condition for terminal voltage across a secondary cell to be equal to its emf?
The condition for the terminal voltage across a secondary cell to be equal to its emf is when there is no current flowing through the cell. When there is no current, there is no voltage drop across the internal resistance of the cell, and thus the terminal voltage equals the emf.
What is the term for he phenomenon of emf development between two different metals placed in contact?
The term for the phenomenon of emf development between two different metals placed in contact is called the thermoelectric effect. This effect occurs because of the temperature difference between the two metals, which creates a potential difference or voltage.
What is a device that provides an emf?
what is an led
What is emf source?
there are two kinds of "EMF" electroMagnetic field and Electromotive force. the former is given off by electricity through a conductor (it doesn't have to be a coil or have a core) the latter can be magnetic flux or electromagnetic waves.

What is a battery clip used for?
A battery clip is used to connect a battery securely to a device or circuit by attaching to the battery terminals. It provides a convenient way to make and break the connection between the battery and the device without needing to solder the wires directly to the battery terminals.
What is voltmeter and thermometer?
Voltmeter is a device to measure EMF and potential difference in terms of volts Thermometer is a device to measure the temperature in terms of K(kelvin),C(Celsius) F(Fahrenheit)
Do EMF apps work to accurately measure electromagnetic fields?
EMF apps may not always accurately measure electromagnetic fields. Their effectiveness can vary depending on the app and the device it is used on. It is recommended to use professional equipment for precise measurements.
How are emf measured?
emf in volts
Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.
Can you define the entertainment device?
A device or gadget which provides entertainment via the means of media
While discharging which is greater TPD or EMF?
EMF is greater
When was EMF - band - created?
EMF - band - was created in 1989.
