What is the direction of magnetic field in a bar magnet?
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
What is magnetic moment of a bar magnet?
The magnetic moment of a magnet is a quantity that determines the torque it will experience in an external magnetic field. Magnetic moment is defined as a vector relating the aligning torque on the object from an externally applied magnetic field to the field vector itself.
Can you calculate magnetic dipole moment of the bar magnet?
Answer: A magnetic dipole consists of two equal and opposite magnetic charges having pole strength +m & -m separated by finite distance ‘2l’. Magnetic Dipole Moment: The magnetic dipole moment is defined as the product of the pole strength and the magnetic length of a magnet.
What is the magnetic moment of fe2+?
The spin magnetic moment of Fe+2 is 4.89 B.M. (Bohr Magneton). Bohr Magneton is the unit of spin magnetic moment.
What is magnetic torque?
The magnetic torque, τ, experienced by a single particle of volume V and domain magnetization Md whose moment is oriented at angle θ to applied induction B is given by τ=mHsinθ where m=MdV is the magnetic moment of the particle.
How do you calculate magnetic torque?
The torque on the dipole is τ = µ×B, where B is the external magnetic field. The magnitude of this torque is µB sinθ, where θ is the angle between B and µ (that’s just definition of cross-product).
What is the normal of a loop?
Torque causes an object to spin around a fixed axis. Each loop of current has a direction associated with it: its normal vector is perpendicular to the loop, in the direction given by the right thumb when the right fingers curl in the direction of the current.
Is normal force constant in a loop?
The normal force and a component of the weight point toward the center of the loop (the component perpendicular to the loop), so they get to be the centripetal force.
How do you find the normal force of a loop?
The magnitude of the force of gravity acting upon the passenger (or car) can easily be found using the equation Fgrav = m•g where g = acceleration of gravity (9.8 m/s2). The magnitude of the normal force depends on two factors – the speed of the car, the radius of the loop and the mass of the rider.
What is the centripetal acceleration at the top of a loop?
If the loop has a radius, r, the centripetal acceleration at the top will be a0=2g h0/r. The centripetal accelerations at the side and at the bottom are immediately obtained from the value at the top as (a0 + 2g) and (a0 +4g), respectively.
How fast does a car have to go to do a loop de loop?
A little under 25 miles an hour, at least. You need the centripetal force required (mass times the square of speed divided by radius) to be equal to or greater than gravitational force (mass times the acceleration due to gravity (g)). The speed requires varies with the square root of the radius.
Can a car make it around a loop?
Jaguar had stunt driver Terry Grant do just that, performing an incredible, record-breaking 360-degree loop-the-loop in a new F-PACE SUV earlier this week. It’s a new Guinness World Record for “the largest ever loop-the-loop completed by a car.” Plus it’s an SUV, and not just some souped-up roadster.
Has a car ever done a loop the loop?
The largest loop the loop in a car measures 19.49 m (63 ft 11 in) and was achieved by Terry Grant (UK) during Riyadh season, in Riyadh, Saudi Arabia, on 25 November 2019.
What does loop the loop mean?

What is the meaning of loop?
in/on a loop If something runs in a loop, or is on a loop, it runs continuously, so that the same things are repeated again and again: The tape ran in a continuous loop, repeating the same songs over and over.
What does it mean when someone says keep me in the loop?
Explanation: To keep someone in the loop is to keep them informed/updated. on a plan or project. In the first example, Seth asks John to keep. him in the loop / keep him informed about Marty’s party.
Does thanks for keeping me in the loop mean?
Explanation: “Loop” is a cycle or a continual circular motion. When you are not in the circle, then you don’t know what is going on. So being in the loop is indicating that you are aware of the situation. Being kept in the loop is asking someone to keep you informed about what is happening.
How do you keep someone in a loop?
To keep someone informed about and/or involved in something, such as a plan or project, especially that which involves or pertains to a specific group. We’ve hired a new intern to help you with data entry, so be sure to keep her in the loop about the project.
What is the meaning of loop in email?
From Wikipedia, the free encyclopedia. An email loop is an infinite loop phenomenon, resulting from mail servers, scripts, or email clients that generate automatic replies or responses. If one such automatic response triggers another automatic response on the other side, an email loop is created.
Can you loop me in the email?
If you want to add someone to a chain, loop them in and add a note in the email letting everyone else in the conversation know that you’ve done so. We use a simple formula: “+Name is now on the thread.”
How do you loop multiple people in an email?
How do I share an email using Loops?
- Select an email you would like to share.
- Tap the Loop in @somone tab at the bottom of the email.
- Select someone from the pop-up or type the name of who you would like to share the email with.

How do you tell someone you forgot to their CC?
By far the easiest and most effective way is to re-send the original email – immediately – to the original recipients plus the one you forgot, with a brief note at the top saying “Re-sent with amended cc field”.
