Why is the deflection in the galvanometer reversed when the magnet is moved in and out in a solenoid?
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.

Why galvanometer show opposite deflection?
A galvanometer shows opposite deflection because the current flowing through it causes a magnetic field that interacts with the permanent magnet inside the galvanometer. The direction of the magnetic field determines the direction of deflection of the needle, resulting in opposite deflection depending on the direction of current flow.
What are the main parts of a galvanometer listed?
The main parts of a galvanometer are the coil, a magnet, a spring, a pointer, and a scale. The coil is connected in series with the circuit and produces the magnetic field. The magnet provides a magnetic field that interacts with the coil's field, causing deflection of the pointer. The spring provides the restoring force to bring the pointer back to its original position, and the scale is used to measure the deflection.
What is the basis of the function of a galvanometer?
The function of a galvanometer is based on the interaction between a magnetic field and an electric current passing through a coil of wire. When a current flows through the coil, it creates a magnetic field that interacts with a permanent magnet, causing a deflection of the needle on the galvanometer scale.
What happens to the path of the cathode ray when the orientation of the magnet is reversed?
When the orientation of the magnet is reversed, the path of the cathode ray will also be reversed. This is because the cathode ray consists of negatively charged particles that are deflected by the magnetic field, so changing the orientation of the magnet will change the direction of the deflection.
Steps in making a galvanometer?
Wind a coil of wire around a bobbin to create the coil, which will serve as the moving element of the galvanometer. Attach a pointer or index needle to the coil to indicate the deflection caused by the current passing through the coil. Place the coil and pointer assembly within a magnetic field produced by a permanent magnet to allow for the deflection of the pointer in response to current flow. Connect the coil to a calibrated scale to measure the amount of current based on the deflection of the pointer.

What are examples of galvanometer?
Some examples of galvanometers include moving-coil galvanometers, moving-magnet galvanometers, and digital galvanometers. These devices are used to measure small electric currents through the deflection of a needle or pointer on a scale.
What does a magnet field in a solenoid resemble?
a bar magnet
What happens to a galvanometer when a magnet is flicked across the coil?
It should deflect to the left (negative) based on the experiment I did a few days ago in lab but I could be wrong. ============================= Doesn't that depend on which end of the coil goes to which end of the meter ?? After you finished the experiment and made note of the meter's deflection, you could leave everything exactly as it is, but get up, walk around to the other side of the table with the magnet, insert the S-pole into the other side of the coil, and I guarantee the meter would deflect in the opposite direction. The configuration is not adequately specified in the question.
How a solenoid may be used to demagnatise a bar magnet?
To demagnetize a bar magnet using a solenoid, the magnet can be placed inside a solenoid and the current can be gradually decreased to zero. This process disrupts the alignment of magnetic domains within the magnet, leading to demagnetization. The alternating current can also be used for more effective demagnetization.
What are the parts of galvanometer and its function?
five basic parts1. A U-shaped permanent magnet with concave poles.2. Flat rectangular coil of thin enameled insulated wire 'C'.3. A soft iron cylinder 'B'.4. A pointer or needle.5. A scale.
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.
