formal introduction to a role or group
The official time when someone is welcomed into a new job, position, or group and is given first information or training.
Padrão de uso:
the induction of [someone] into [a job/organization]
Erro comum:
Learners sometimes confuse "induction" with "introduction" and use *induction* in everyday informal contexts where native speakers would say "Let me introduce you." "Induction" is usually used for formal or organized processes in workplaces, schools, or official groups, not for casual social meetings.
Sinónimos
orientation (Common in workplaces and schools; focuses slightly more on practical information and training than on formality or ceremony.)
|
onboarding (Business jargon; emphasizes the whole process of helping new employees adjust to a job or company.)
Antónimos
dismissal (Refers to formally removing someone from a job, the reverse of formally bringing them into it.)

reasoning from examples to general rule
A way of thinking where you look at many examples and then say what is usually true for all similar cases.
Padrão de uso:
induction from [examples/observations] to [a general rule]
Erro comum:
Learners may confuse "induction" with "deduction" because they look and sound similar. Remember: induction = from specific examples to a general rule; deduction = from a general rule to a specific conclusion.
Sinónimos
generalization (Focuses on the end result (a broad statement) rather than the careful reasoning process; often used more critically.)
|
inductive reasoning (A near-equivalent phrase that explicitly names the type of thinking involved.)
Antónimos
deduction (Deduction moves from general rules to specific conclusions, the opposite direction of induction.)

medical starting of childbirth
A hospital process where doctors make labor start using medicine or other medical methods.
Padrão de uso:
the induction of [labor] at [time]
Erro comum:
Learners may think "induction" here just means any start of labor. In medical English it usually means labor is started by doctors, not that it begins by itself. Also, this sense is almost always used in the phrase "induction of labor" or "labor induction."
Sinónimos
labor induction (A more specific term that clearly says the induction is about childbirth.)
Antónimos
spontaneous labor (Refers to labor that begins naturally, without medical induction.)

electromagnetic production of electricity
A physical process where a changing magnet field makes electricity in a nearby wire or metal.
Padrão de uso:
induction of [current/voltage] in [a conductor]
Erro comum:
Learners may confuse "induction" with "inductor" or use it to mean any electric effect. In physics, this sense of "induction" specifically describes current or voltage created by a changing magnetic field, not just any flow of electricity.
Sinónimos
electromagnetic induction (More specific technical term; explicitly names the electromagnetic cause of the effect.)
Antónimos
conduction (Conduction refers to transfer of electric charge or heat through a material, contrasted with the generation of current by induction.)

Exemplos
- Generators use electromagnetic induction to turn mechanical motion into electricity.
- Faraday’s experiments on induction changed the history of electrical engineering.
- Induction heating is used in modern cooktops to heat pans quickly and efficiently.
- The design of the induction motor makes it robust and easy to maintain.
- Students repeated a classic experiment to observe induction in a simple coil and magnet setup.
Exemplos para aprendentes

mathematical proof by induction
A way to prove a math rule is true for all whole numbers by proving it for the first number and then proving that if it is true for one number, it is also true for the next number.
Padrão de uso:
proof by induction on [a variable]
Erro comum:
Learners sometimes mix this mathematical sense of "induction" with the logical sense of induction from examples. In mathematics, "induction" almost always refers to the specific proof method "mathematical induction," not to reasoning from many examples.
Sinónimos
mathematical induction (Standard full term for this proof technique; identical in technical use.)
Antónimos
direct proof (A contrasting proof style that does not rely on an inductive step from one case to the next.)
