What is the shape of magnetic lines force in case of a straight current carrying conductor?
The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
What is a changing electric current that carries information is called a?
A changing electric current that carries information is called a signal. This signal can be in the form of varying voltage levels or frequencies that can represent data or enable communication between electronic devices.
What is eletric current?
Current is basically, the rate of flow of charges through a conductor or wire. It is commonly denoted by the alphabet I and measured in Amperes. I = ne/t n = no of electrons e = charge on an electron t = time taken for electron to move
Why any electric wire get suddenly cool when electric current cutoff?
Heat in an electric wire is mainly caused by the rapid movement and collision of electrons as they flow along it, when an electric current is cut off, the flow is greatly reduced causing a huge drop in temperature.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
Energy is a current carrying coil is stored in the form of?
The energy in a current-carrying coil is stored in the form of magnetic energy in the magnetic field produced by the coil. This magnetic energy is a result of the interaction between the current flowing through the coil and the magnetic field it generates.
How would you sketch the magnetic field lines of a coil with electric current?
The magnetic field lines around a coil carrying an electric current form concentric circles that are perpendicular to the coil. The direction of the magnetic field lines can be determined using the right-hand rule: if you curl the fingers of your right hand in the direction of current flow, your thumb points in the direction of the magnetic field lines inside the coil.
What is the shape of magnetic lines force in case of a straight current carrying conductor?
The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.
Is a magnetic field line about a current-carrying wire extend radially from the wire true?
No, magnetic field lines around a current-carrying wire form concentric circles perpendicular to the wire. The direction of these circles is determined by the right-hand rule.
When a current-carrying wire is made to form a coil around a piece of iron the device is called?
A solenoid with iron core also known as electromagnet
Path made for an electric current?
A path made for an electric current is classified as a conductor and can come in the form of many shapes and sizes.
Electric current in metals result form the flow of?
Electrons.

What do you mean by heating and magnetic effect of electric current?
When electric current travels through a conductor, there is always resistance. This resistance causes some of the energy of the current to express as heat. Additionally, the movement of the current causes a magnetic field to form around the current in a clockwise direction. This principle is what allows coil heaters and induction motors to operate.
Pattern of field lines due to solenoid carrying electric current?
From my text book: You'll see that inside a solenoid the magnetic field is etremely strong, this can be used to magnetise objects. The field around it is exactly the same as the field around a bar magnet. Concentrated inside the solenoid and gradually getting more spaced out the further away
Which particles carry an electric current around a circuit?
The particles that carry charge around a circuit are electrons. In some semiconductors, missing electrons in a crystalline structure (of silicon or germanium), caused by adding special impurities, form spaces called "holes" where there is a missing electron. These "holes" can also travel but, in the end, it is electrons that move in the opposite direction to fill those holes that carry the current.
