Answer: a) Magnetic field
Explanation: The magnetic field is the region around a magnet where its magnetic force can be detected.
Answer: d) Ferromagnetic materials
Explanation: Ferromagnetic materials such as iron, nickel, and cobalt can be magnetized because they have unpaired electrons in their outer shells that can be aligned to create a magnetic field.
Answer: d) Lodestone
Explanation: Lodestone is a naturally occurring magnetized mineral that is made up of magnetite.
Answer: b) Paramagnetism
Explanation: Paramagnetism is a type of magnetism that is only temporary and occurs when a material is placed in an external magnetic field. This type of magnetism is caused by the alignment of magnetic moments in the material with the external magnetic field, but it disappears once the external field is removed.
The onreadystatechange event in AJAX is used to define a callback function that will be executed when the state of the XMLHttpRequest object changes, indicating different stages of the request-response cycle.
The POST method is commonly used in AJAX requests for sending data to the server. It allows for the transmission of data in the request body, making it suitable for sending large amounts of data securely.
The Same-Origin Policy in AJAX restricts cross-origin requests by preventing web pages from making requests to a different domain than the one that served the web page, enhancing security.
JSON, in the context of AJAX, stands for JavaScript Object Notation. It is a lightweight data interchange format used to transmit data between a client and a server.
In jQuery, the $.ajax() method is used to send AJAX requests. It provides a flexible and powerful way to make asynchronous requests to the server and handle responses.
The readyState property in AJAX is used to track the status of the XMLHttpRequest object. It indicates the current state of the request-response cycle, allowing developers to handle different stages accordingly.
