According to Coulomb's law, the electrostatic force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of distance between their centers.
And Biot Savart's law gives the magnetic field at point due to a small current element. And, according to Biot Savart's law ,the magnitude of magnetic field is directly proportional to the product of current element Idl and Sin theta and inversely proportional to the square of distance between two point charges.

Similarities and differences between Biot-savart law and coulombs law?
similarities:1. field at any point vary inversely at the square of the distance.2. both obey superposition principle3. the magnetic fields linear in the source just as electric field.dissimilarities:1. E is produced by a scalar source (q) where as B is produce by vector source (Idl)2. E is acting along the displacement vector where as B acts perpendicular to Ixr.3. E is not depended of θ where as B depends upon θ.
What is the differential form of Biot and Savart law?
Hi this is it : dB=m0I/4pi (dl x r) / |r3|, I hope this works for you.you can take r unitary if you change |r3| by |r2| and make cross product alotmuch simpleThis is took of my class of Electrodynamics 2
Magnetic field due to a current through a circular loop?
The magnetic field due to a constant current through a circular loop is the same shape, outside the loop, as the field due to a bar magnet. At the centre of the loop the field can be found, using the Biot-Savart Law, to be (Equation 1: URL in related links), where ?0 is the permeability of free space, I is the current through the loop, R is the radius of the loop and z-hat is a unit vector perpendicular to the plane of the loop. The field on the axis of the loop can be found, again using the Biot-Savart Law, to be (Equation 2: URL in related links), where z is the distance from the centre of the loop along its axis and all other symbols have the same meaning as in the previous equation.
What is the meaning of Biot-Savar's equation?
1) What is the definition of dielectric permittivity on the basis of Maxwell equations? 2) What is Poisson equation of Electrostatics? Derive the Poisson equation from Maxwell equations. 3) Write the Biot-Savar equation. What is the meaning? 4) Derive a wave equation of a plain electromagnetic wave from Maxwell equation.
What is the difference between electromagnetic induction and magnetic induction?
Electromagnetism is first discovered by Oersted. Electromagnetic induction first found by Michael Faraday. Electromagnetism is the phenomenon in which magnetism is produced when electric current flows in a straight wire. This is the conversion of electrical energy into magnetic energy. But electromagnetic induction is the phenomenon in which electric current is produced in a wire as it cuts the magnetic lines of force. Here in the presence of magnetic energy mechanical energy gets converted into electrical energy. The former is applied in fans, motors etc. The later is utilised in generators. In an electrical bell, electromagnetism plays an important role. In case of choke, electromagnetic induction serves in a nice way. Former has Biot-Savart law, Ampere's circuital law, Lorentz force law, Fleming's left hand rule, Right hand thumb rule. The latter has Faraday's laws, Lenz law, Fleming's right hand rule.
Can you prove Biot-Savart's law directly?
No, it was found by expirement.
Where will you use ampere circuital law in preference to biot savart law?
Depends on whether a path integral or a normal integral is easier to determine.
Derivation of amperes law from biot savart law?
----> ampere's law :which is to be used while finding magnetic fields inside the enclosed surface. we are allowed to use it to any surface however the surface have to be in such ways that the path must pass through the point and the path must have enough symmetry so that is constant along the large path of it!----> Biot Savart law : we often use biot savart to find magnetic fieldsgenerated by an electric current carrying wire of radius "r" and since the radius is perpendicular with I we don't worry about messy integration!thus we left with : dB =( µ_0 Idl) / (4πr^2)also knowing that l = 2πr helps so we substitute it in! and we eventually end up with : dB =( µ_0 Id2πr) /(4πr^2)Thus B = µ_0 I / 2πrCombining Ampere Law to Biot savart.Thus we can derive Biot savart from ampere by the following:§ B.dl = µ_0 I (encl)B § dl = µ_0 I (encl) hence B (2πr) isB(2πr) = µ_0 Iso B = (µ_0 I) / 2πrfaith nshuti.

Prove that current can be a source of magnetism?
A classic and ancient experiment is to get a compass, a battery (9volt is fine), and some wire. Notice that the compass changes when the circuit is closed (wire connected to the two terminals). You can also see that the compass gets affected less when it is far from the wire versus next to it. If your interested in the math behind the experiment, you may want to do some research on the Biot-Savart Law. The Biot-Savart law describe the magnetis field when the current is constant, or not time-varying. A more general form of the equation is called Ampere's Law, and the more general case of that is Maxwell's equations.
