What will be deflection in compass needle of a magnet when a current carrying wire is placed over it?
The compass needle will turn until it's perpendicular to the wire, provided the current in the wire is enough to generate a magnetic field around the wire that's strong enough to swamp out the effects of the Earth's magnetic field. (That doesn't take much current.)
To use a needle and cotton?
Thread the cotton through the eye of the needle, leaving a tail to hold onto. Hold the needle steady and start sewing by pushing the needle in and out of the fabric. Remember to knot the thread at the end to secure your stitches.
Can you use speaker wire for power wire for an amp?
It is not recommended to use speaker wire for power wire for an amp. Speaker wire is not designed to handle the high current load required for powering an amplifier. It is best to use appropriate gauge power wire to ensure safety and optimal performance of your amplifier.
What magnetized steel needle that aligns with the magnetic of the earth is a?
A compass needle is a magnetized steel needle that aligns with the Earth's magnetic field. Its use allows for determining directions such as north, south, east, and west.
What can you use to cut wire?
You can use wire cutters, pliers, or scissors to cut wire depending on the thickness and material of the wire. Be sure to choose the appropriate tool for the job to ensure clean and safe cuts.
When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
How do you use a compass to find the flow through a wire?
A compass can be used to find the flow of current through a wire by placing the compass near the wire. The needle of the compass will align with the magnetic field created by the current flowing through the wire, indicating the direction of the current flow. The needle will point in the direction from which the current is coming.

Why does a compass needle placed near a current carrying wire show deflection?
A compass needle placed near a current-carrying wire shows deflection because the moving charges in the wire create a magnetic field around the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align with the direction of the current flow in the wire.
What will be deflection in compass needle of a magnet when a current carrying wire is placed over it?
The compass needle will turn until it's perpendicular to the wire, provided the current in the wire is enough to generate a magnetic field around the wire that's strong enough to swamp out the effects of the Earth's magnetic field. (That doesn't take much current.)
How do you make galvanoscope?
To make a simple galvanoscope, you would need a horseshoe magnet, a thin wire, a small compass needle, and a stand. The wire is wound around the magnet, and the compass needle is suspended in the coil of wire. When an electric current flows through the wire, it creates a magnetic field that deflects the compass needle, allowing you to visualize the current.
Does the compass needle change direction if the flow of electricity in the wire near it is reversed?
Yes, the compass needle will change direction if the flow of electricity in the wire near it is reversed. This is because the flow of electricity creates a magnetic field around the wire, which can interact with the magnetic field of the compass needle.
What happens to the needle of a compass as a wire carrying electric current is placed across it?
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
Determine the direction in which a compass needle will point when held above a wire with positive charges moving west?
The compass needle will point towards the wire, perpendicular to the current flow. Since the positive charges are moving west, the magnetic field generated by their movement will induce a force on the compass needle causing it to point towards the wire.
Why the magnetic needle gets reflected when placed near a current carrying wire?
The magnetic needle gets deflected near a current-carrying wire due to the magnetic field generated by the current. The magnetic field induces a force on the needle, causing it to align or deflect towards or away from the wire. This phenomenon is a result of the interaction between the magnetic field and the magnetic properties of the needle.
To use a needle and thread?
To use a needle and thread could be called sewing.To use a needle and thread could be called quilting. To use a needle and thread could be called embroidery. To use a needle and thread could be called suturing.
How is a guide wire use in an angiographic procedure?
guide wire is fed through the outer needle into the artery to the area that requires angiographic study. A fluoroscope displays a view of the patient's vascular system and is used to direct the guide wire to the correct location
