How do the north and south poles of a solenoid change with the direction of current flow?
The north and south poles of a solenoid change depending on the direction of the current flow. When the current flows in one direction, the north pole of the solenoid is at one end and the south pole is at the other end. If the current flows in the opposite direction, the poles switch places, with the south pole at the end where the north pole was and vice versa.

What do north and south poles of a solenoid change with?
The north and south poles of a solenoid change with the direction of electric current passing through the coil. When current flows in one direction, one end becomes the north pole and the other end becomes the south pole. Reversing the direction of current will reverse the polarity of the solenoid.
Predict whether a solenoid suspended by a string could be used as a compass?
Yes, a solenoid suspended by a string can be used as a simple compass. When a current passes through the solenoid, it generates a magnetic field that aligns with the Earth's magnetic field, indicating the North-South direction. By observing the orientation of the solenoid when a current passes through it, one can determine the direction of the compass.
Can a solenoid suspended by a string be used as a compass?
A solenoid can be used as a compass when a DC current is going through it because when a current is going through the solenoid, the magnetic field lines are nearly uniform and perfectly parallel inside of it, giving it essentially a north pole and south pole.
What rule is used to find out polarity of a current carrying solenoid?
To determine the polarity of a current-carrying solenoid, use the right-hand grip rule. Point your right thumb in the direction of the conventional current flow in the solenoid coil (from positive to negative) and wrap your fingers around the coil in the direction of the current. Your outstretched fingers will then indicate the polarity of the solenoid: the tip of your fingers shows the north pole, while your palm indicates the south pole.
What is the strength and direction of the magnetic field outside of a solenoid?
The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.
What do north and south poles of a solenoid change with?
The north and south poles of a solenoid change with the direction of electric current passing through the coil. When current flows in one direction, one end becomes the north pole and the other end becomes the south pole. Reversing the direction of current will reverse the polarity of the solenoid.
What lets the north pole and south pole of a solenoid be able to change poles?
The poles of the solenoid depend on the direction of the current through the coil. The current reverses if you just reverse the polarity of the voltage between the ends of the coil. Heck, if you energize the coil with AC, you can do that 120 times every second.

How does the north and south poles on a magnet change the solenoid?
The north and south poles of a magnet create a magnetic field that interacts with a solenoid, which is a coil of wire. When a magnet is moved near the solenoid, the changing magnetic field induces an electromotive force (EMF) in the wire, generating an electric current if the circuit is closed. The direction of the induced current depends on the orientation of the magnet's poles relative to the solenoid, following Faraday's law of electromagnetic induction. This principle is fundamental in applications like electric generators and transformers.

How the direction of EMF depends on the direction of current?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles. Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.
What is the strength and direction of the magnetic field outside of a solenoid?
The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.
The gulf stream is deflected by north America causing the current to change direction what is this concept called?
Continental deflection
What happen to an electromagnet's field if the direction of the current ic reversed?
If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.
Why do the north east trade winds change direction in ganga valley?
THE north east trade wind change their direction because
What happen when you change the direction of current in an electromagnet?
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
